Quick Answer
Aura tools are instruments and practices used to sense, read, cleanse, and strengthen the bioelectric and subtle energy field surrounding the human body. The most important tool is the practitioner's own trained awareness. Secondary tools include crystals, pendulums, tuning forks, sound bowls, biofeedback cameras, and smudging herbs. This guide covers the science and tradition behind aura work, the primary tools and how to use them, and a comprehensive practice framework for beginners and experienced practitioners alike.

Key Takeaways
- Multi-layered field: The aura is traditionally understood as a multi-layered energy field reflecting physical, emotional, mental, and spiritual dimensions simultaneously.
- Science supports the basic phenomenon: Biophoton emission, bioelectric fields, and electromagnetic body fields are measurable; traditional aura layer frameworks are interpretive models applied to these phenomena.
- Hands are the primary tool: Sensitivity training for your own hands is more fundamental than any purchased instrument.
- Regular cleansing matters: Daily energy hygiene prevents accumulation of discordant energies absorbed from people and environments.
- Practice develops perception: Aura perception is a learnable skill. Most people notice changes within two to four weeks of consistent daily practice.
What Is the Aura?
The aura is the energetic field that surrounds, interpenetrates, and extends beyond the physical body. Across thousands of years of human culture, from the halos in Christian iconography to the prana body in Vedic tradition to the wei qi in Traditional Chinese Medicine, virtually every spiritual and healing tradition has described some version of an energy body that transcends but includes the physical.
In contemporary Western esoteric traditions, the aura is typically described as a luminous egg-shaped field extending anywhere from a few centimetres to several metres around the body, depending on the individual's health and spiritual development. Trained clairvoyants and energy healers perceive the aura as layered, with each layer corresponding to a different dimension of experience: physical, emotional, mental, and spiritual.
Why Aura Work Matters Practically
The aura is not a decorative spiritual concept. It is the interface between your inner world and the outer environment. Just as the skin is the organ that mediates between the body's interior and the external world, the aura mediates between your emotional and mental interior and the energetic environment you inhabit. Damage, depletion, or contamination of the aura has real consequences for mood, health, relationships, and spiritual development. Conversely, a strong, clear, and well-maintained aura supports vitality, emotional stability, and conscious spiritual functioning.
Energy healer and teacher Barbara Brennan, whose decades of work with clients and research at NASA are documented in her landmark book Hands of Light (1987), describes the human energy field as a highly structured, organised system of energy that reflects and influences all aspects of human functioning. Brennan's detailed observational accounts, based on working with thousands of clients, provide one of the most comprehensive maps of the aura structure available in Western literature.
Scientific Research on Biofields
While the traditional and esoteric frameworks for understanding the aura go beyond what current science can fully verify, several areas of scientific research provide substantial support for the basic phenomenon of a measurable energy field surrounding the body.
Biophoton Research: Fritz-Albert Popp
German biophysicist Fritz-Albert Popp at the University of Marburg spent decades documenting the emission of ultra-weak light, called biophotons, from living cells. His research, published in journals including Experientia and the Journal of Biophotonics, established that this light emission is not random thermal radiation but coherent and structured, suggesting it serves a biological information-carrying function. Popp's hypothesis that biophoton emission is a fundamental mechanism of biological communication within and between organisms provides a scientific basis for understanding how the aura field might function as an information system.
Harold Saxton Burr, professor of anatomy at Yale Medical School, spent four decades measuring what he called L-fields or life fields surrounding living organisms. His book Blueprint for Immortality (1972) documented that these bioelectric fields could predict illness before physical symptoms appeared, correlated with emotional states, and changed measurably during healing. Burr's work was ahead of its time and is increasingly validated by contemporary bioelectricity research.
HeartMath Institute research on the heart's electromagnetic field has documented that the heart generates an electromagnetic field extending approximately three to five feet beyond the body in all directions. This field interacts with the fields of others in proximity and carries information about the person's emotional state. HeartMath researchers have shown that these field interactions influence the autonomic nervous systems of people in close proximity, providing a measurable mechanism for what energy practitioners describe as field exchange during healing work.
The Aura Layers Explained
Traditional and contemporary energy healing systems differ somewhat in their detailed maps of the aura layers, but most converge on a model of five to seven distinct layers, each associated with a different dimension of experience and a different chakra system level.
The Seven Aura Layers
- Etheric body (Layer 1): The layer closest to the physical body, extending two to five centimetres from the skin. It is a bluish-grey energy template of the physical body and reflects physical health most directly. Illness often appears in this layer before manifesting physically.
- Emotional body (Layer 2): Extends five to ten centimetres from the body. Carries the current emotional state. Highly variable in colour and consistency, moving and shifting with emotional experience.
- Mental body (Layer 3): Extends ten to twenty centimetres. Contains thought patterns, beliefs, and mental structures. Often perceived as a yellow or yellow-white light that intensifies around the head during concentrated thinking.
- Astral body (Layer 4): Extends approximately thirty centimetres. The bridge layer between lower and higher bodies. Contains relationship cords and carries the quality of our interpersonal connections. Often appears in pastel rainbow hues.
- Etheric template (Layer 5): Extends approximately fifty centimetres. The energetic template for the physical etheric layer, existing in a higher octave. Related to will and creative power in the physical world.
- Celestial body (Layer 6): Extends approximately seventy centimetres. The emotional level of the spiritual plane. Carries spiritual ecstasy, unconditional love, and connection to the divine. Often perceived as iridescent opalescent light.
- Ketheric template (Layer 7): The outermost layer, extending approximately one metre. The mental level of the spiritual plane. Contains the complete soul plan and the accumulated wisdom of all lifetimes. Perceived as a golden grid of light.
Aura Colours and Their Meanings
Aura colour interpretation is not a fixed system. Different traditions and practitioners use somewhat different colour maps. The following represents a widely used synthesis that has emerged through the convergence of multiple traditions in contemporary energy medicine practice.
Aura Colour Interpretations
Red in the aura typically indicates strong physical vitality, passion, courage, and grounded connection to the physical world. A clear, vibrant red is healthy and energising. A muddy or dark red can indicate anger, survival stress, or physical exhaustion. Root chakra energy.
Orange relates to creativity, emotional vitality, sexual energy, and interpersonal joy. Bright orange indicates a highly creative person with robust emotional expressiveness. Dull orange may indicate emotional blockage or addictive patterns. Sacral chakra energy.
Yellow in the aura correlates with mental activity, intellectual energy, personal power, and optimism. Bright yellow around the head indicates active, clear thinking. A murky yellow may indicate overthinking, anxiety, or ego-based mental patterns. Solar plexus chakra energy.
Green relates to healing, compassion, balance, and heart energy. A clear, vibrant green indicates a natural healer with genuine compassion. Muddy green may indicate jealousy, resentment, or blocked heart energy. Heart chakra energy.
Blue indicates communication clarity, emotional depth, spiritual sensitivity, and truth. Clear blue corresponds to someone with excellent communicative and listening abilities. Dark or murky blue may indicate unexpressed truths or communication blockages. Throat chakra energy.
Indigo relates to intuition, psychic perception, deep wisdom, and inner vision. Indigo in the aura is commonly associated with highly developed intuitive capacities and a contemplative inner life. Third eye chakra energy.
Violet or purple relates to spiritual development, connection to higher dimensions, and selfless service. Strong violet in the aura often indicates someone on an active spiritual path. Crown chakra energy.
White or gold indicates a highly purified state, divine connection, and advanced spiritual development. These colours often appear during meditation, healing work, or spiritual experience and are considered indicators of elevated consciousness.
Tools for Sensing the Aura
The most important aura sensing tool is the practitioner's own hands, sensitised through practice. Subsidiary tools include crystal pendulums, tuning forks, dowsing rods, and electronic biofeedback devices. Each tool has different strengths and is suited to different purposes.
Hand Sensitivity Development Exercise
Rub your palms together briskly for fifteen to twenty seconds to activate the energy centres in the hands. Then hold your palms facing each other about thirty centimetres apart. Slowly bring them closer together and notice sensations: tingling, warmth, pressure, or a subtle resistance. The point at which you feel slight resistance is the edge of your hand's bioelectric field interacting with itself. Practise extending and compressing this sensation daily. With three to four weeks of consistent practice, sensitivity to the external aura field of other people and objects typically develops noticeably.
Crystal pendulums are used for dowsing the aura field, detecting areas of density, depletion, or irregularity. A quartz or amethyst pendulum is held steady over the body from a distance of about fifteen to thirty centimetres and allowed to move freely. Most practitioners observe that the pendulum moves in consistent patterns over healthy areas and shifts behaviour over areas of energetic disturbance. This technique is used diagnostically before energy healing sessions.
Tuning forks are increasingly used in aura assessment because they provide auditory feedback about field density. When a vibrating tuning fork is moved slowly through the aura field, practitioners report that the tone changes subtly when moving through dense or disturbed areas. Biofield tuning practitioner Eileen McKusick, whose research spans two decades of clinical work with tuning forks documented in her book Tuning the Human Biofield (2014), describes the aura as a chronological record of experience stored in nested electromagnetic layers, each accessible and treatable through specific frequencies.
How to Read an Aura
Aura reading is a perceptual skill developed through consistent practice. Very few people have immediate natural ability to see auras clearly. Most practitioners develop their perception gradually through deliberate training over months to years.
Beginning Aura Perception Practice
Stand your subject against a plain white or pale neutral wall in indirect natural light. Avoid fluorescent lighting, which interferes with subtle perception. Have the subject stand still and breathe naturally. Soften your gaze: instead of looking directly at the subject, look slightly to the side of their head or shoulders and allow your vision to go slightly out of focus, as if you were looking through them rather than at them. This peripheral, softened mode of vision is more sensitive to the subtle luminosity of the aura than direct focal vision.
In the first sessions, most people notice a slight shimmer or movement just at the skin boundary. This is the etheric layer. With continued practice, colour impression begins to emerge in the peripheral vision. Starting with plants is recommended: sit quietly with a healthy plant against a neutral background and practise the same technique. Plant auras are often simpler and more consistent than human auras and provide a gentle training ground.
Sensing rather than seeing is equally valid and often more reliable for practical purposes. Many excellent energy healers perceive the aura primarily through hand sensitivity, temperature changes, pressure, or intuitive knowing rather than visual impression. Do not discount non-visual aura perception: it is not a lesser version of the skill but a different mode that some people's nervous systems naturally favour.
Aura Cleansing Tools and Methods
Aura cleansing removes accumulated discordant energies from the field, restores coherence, and creates conditions for optimal energetic function. Regular cleansing is considered as necessary for energetic health as regular physical hygiene is for physical health.
Primary Aura Cleansing Methods
- Smudging: White sage, palo santo, cedar, and copal are traditional cleansing smokes used across cultures for clearing the aura and environmental spaces. Move the smudge around your entire body from feet to crown, paying extra attention to areas that feel dense or heavy. Science has confirmed antimicrobial properties in sage smoke. The energetic clearing effect is additionally supported by the ceremonial intention with which the practice is conducted.
- Salt baths: Two cups of sea salt or Epsom salts in a warm bath, soaked for twenty minutes, is one of the most comprehensive aura cleansing practices. Salt is a universal purifying agent across cultures. Magnesium from Epsom salts absorbs through the skin and supports nervous system regulation. Many practitioners add a few drops of lavender, frankincense, or eucalyptus essential oil.
- Sound: Tibetan singing bowls, crystal bowls, tuning forks, and bells are all used to break up and disperse stagnant energy in the aura. The vibration moves through the field and dislodges what has become stuck. Passing a ringing Tibetan bowl slowly around your body or another person's body while maintaining clear cleansing intention is a highly effective practice.
- Selenite wand: Selenite is considered self-cleansing and is used to comb the aura layers. Hold the wand about five to ten centimetres from the body and draw it slowly downward from crown to feet in long strokes, working around the entire body. Shake or cleanse the wand between strokes. This method is used by many Reiki practitioners as a pre and post-session cleansing protocol.
- Running water: Standing under a shower or natural waterfall with clear intention to release what does not serve is a powerful and accessible cleansing method. Many traditions regard moving water as a universal purifier.
- Breathwork: Conscious connected breathwork with the intention on each exhale of releasing accumulated energetic material is a direct and effective cleansing method accessible anywhere. Kapalbhati pranayama, the forceful exhalation breath from the yoga tradition, is particularly associated with clearing the energetic field.
Aura Protection Practices
Protection practices differ from cleansing in that they are preventive rather than restorative. Where cleansing removes what has already accumulated, protection practices create a strengthened and boundaried field that reduces how much discordant material enters in the first place.
The Aura Shield Visualisation
One of the most widely taught aura protection techniques involves visualising the aura field as a luminous sphere surrounding the body and deliberately reinforcing its outer layer. In a morning practice, sit quietly, take three deep breaths, and visualise your aura as a glowing ovoid of light surrounding you completely. See the outer edge as a clearly defined, iridescent boundary. Intend that this boundary allows in only what is genuinely nourishing while remaining permeable to love, connection, and genuine care. Many practitioners add a specific colour: gold for spiritual protection, silver for reflecting back unwanted energies, or blue for calming and clarity.
Crystal allies for protection are a major part of the aura tools toolkit. Black tourmaline is the most widely used protective crystal. It is believed to absorb and neutralise discordant energies before they penetrate the aura field. Many people carry a piece of black tourmaline or wear it as jewellery during times of high exposure to challenging environments or people. Labradorite is used for strengthening the aura's outer membrane specifically. Black obsidian is used for deep, ceremonial protection. Tiger's eye supports grounded confidence.
Strengthening Your Aura Field
A strong aura field is not just about protection from external influences. It reflects and supports overall vitality, coherence, and spiritual development. The practices that strengthen the aura are also the practices that strengthen the whole person.
Daily Practices That Strengthen the Aura
- Meditation: Consistent meditation practice, particularly open awareness or loving-kindness meditation, is one of the most documented practices for developing a coherent, expanded aura field. Experienced meditators consistently show larger and more coherent bioelectric fields in HeartMath measurements.
- Physical exercise: Moving the body activates the etheric body and increases the overall circulation and vitality of the energy system. Practices that combine physical movement with breath awareness, like yoga, tai chi, and qigong, are particularly effective for aura development.
- Time in nature: Natural environments, particularly those with water, trees, and geological features, radiate field qualities that strengthen and attune the human aura. Barefoot contact with the earth, called earthing or grounding, has documented physiological effects on the body's electrical state and is associated with reduced inflammation and improved autonomic nervous system function.
- Conscious nutrition: Fresh, living plant foods carry higher biophoton content than processed foods. Diet choices that increase the body's own biophoton emission and bioelectric coherence support a stronger aura field. Reducing alcohol, which dampens the coherence of the field, is frequently reported to produce noticeable aura effects.
- Emotional processing: Unprocessed emotions are held as tensions and distortions in the emotional aura layer. Emotional release practices, therapy, shadow work, and authentic relational communication all contribute to clearing and strengthening the emotional body.
Kirlian and Aura Camera Technology
Kirlian photography, developed by Semyon Kirlian in the Soviet Union in 1939, captures electrical discharge patterns around objects placed on photographic film with a high-voltage, high-frequency electrical charge applied. The resulting images show a distinctive corona of light around the edges of objects, particularly pronounced around living materials like leaves, fingertips, and plants.
Modern aura cameras, popularised through products like the AuraCam and various biofeedback imaging systems, work differently from Kirlian photography. They use biometric sensors on the hands to measure skin conductance, temperature, and electromagnetic signals, then apply proprietary algorithms to generate a colour display representing the measured states as an aura-like field around a photograph of the subject. These images are real biofeedback data visualised as an aura overlay, not photographs of a subtle energy field in the traditional sense.
What Aura Cameras Actually Show
The scientific value of aura camera readings depends on understanding what they are measuring. The biometric sensors capture real physiological data: autonomic nervous system states reflected in skin conductance and temperature. This data is meaningfully related to emotional states, stress levels, and overall vitality. The colour overlay is an interpretive display of this data rather than a direct image of a subtle energy layer. Used with this understanding, aura cameras are useful biofeedback tools. Treated as literal photographs of the subtle body, they are misleading. The most valuable use of aura camera technology is tracking changes in the same individual over time as they engage with various practices and life changes.
Frequently Asked Questions
What is an aura?
An aura is the energetic field that surrounds and permeates the physical body. In traditional energy medicine systems including Ayurveda, Traditional Chinese Medicine, and various Western esoteric traditions, the aura is understood as a multi-layered field of subtle energy that reflects physical health, emotional states, mental activity, and spiritual development.
Can aura cameras actually photograph the aura?
Modern aura cameras use biofeedback sensors to measure hand temperature, skin conductance, and electromagnetic signals, then generate a colourful field display. These images are real biofeedback representations but are interpretive constructs rather than direct photographs of a subtle energy field. Kirlian photography captures electrical discharge patterns rather than the aura as traditionally understood.
What do aura colours mean?
Red indicates physical vitality and passion. Orange relates to creativity and emotional expressiveness. Yellow corresponds to mental activity and personal power. Green relates to healing and heart energy. Blue indicates communication and spiritual sensitivity. Indigo connects to intuition and deep introspection. Violet relates to spiritual development. White or gold often appears in highly spiritually developed individuals or during peak experiences.
How do I learn to see auras?
Begin by practising peripheral vision observation in soft lighting with a subject against a plain white wall. Soften your gaze and look slightly to the side of the subject rather than directly at them. With consistent practice over several weeks, most people begin to notice subtle luminosity around the body. Starting with plants before attempting human auras is recommended.
What is an aura cleanse?
An aura cleanse is a practice intended to clear accumulated discordant or foreign energies from the aura field. Methods include smudging with sage or palo santo, salt baths, breathwork with visualisation, sound healing with Tibetan bowls or tuning forks, and hands-on energy healing practices like Reiki. Regular aura cleansing is considered important for maintaining energetic health.
What tools are used to sense the aura?
The primary tool is the practitioner's own hands and sensory awareness, trained through practice. Crystal pendulums are used for dowsing the aura field. Kirlian and biofeedback aura cameras provide electronic readings. Selenite and clear quartz wands are used for sensing and combing the aura field. Tuning forks reveal density and disturbance through auditory feedback when moved through the field.
How often should I cleanse my aura?
The frequency depends on your lifestyle and sensitivity. People in high-contact service roles or those who are highly sensitive may benefit from brief daily practices with deeper monthly clearing sessions. People living quieter lives may find weekly cleansing sufficient. Your own sense of energetic density or depletion is the best guide.
Can negative people actually damage your aura?
From an energetic perspective, prolonged exposure to chronically negative or manipulative people can leave imprints in the aura field that affect mood, energy, and perception. Energy healers across traditions consistently report finding foreign energetic material in the fields of their clients that correlates with difficult relationships. Whether understood energetically, psychologically, or neurologically, the practical experience of needing to clear oneself after certain interactions is widely reported.
What crystals are best for aura work?
Black tourmaline absorbs and neutralises discordant energies and is widely used for protection. Selenite is used to comb and clear the aura layers. Clear quartz amplifies and clarifies. Labradorite strengthens the aura's outer boundaries. Amethyst supports spiritual clarity and calm. Rose quartz softens and fills areas of the aura depleted by grief or loss.
Is there scientific evidence for auras?
Research on biophoton emission from living organisms by Fritz-Albert Popp at the University of Marburg has demonstrated that all living cells emit coherent ultra-weak light. Harold Saxton Burr at Yale documented bioelectric life fields surrounding living organisms that correlated with health states. HeartMath Institute research has documented electromagnetic fields extending several feet beyond the body. These findings provide a biological basis for the field phenomena described in aura traditions.
What is the difference between aura layers?
Most traditions describe multiple aura layers corresponding to different dimensions of experience. The etheric body reflects physical health. The emotional body carries the emotional state. The mental body holds thoughts and belief patterns. Higher layers relate to spiritual development. These layers interact with each other, and illness often appears in the etheric field before manifesting physically.
Can I strengthen my own aura?
Yes. Regular meditation, physical exercise, time in nature, consistent sleep, positive emotional practices, and deliberate spiritual work all strengthen and expand the aura field. Practices specifically targeted at the aura include breathing exercises visualised as filling and brightening the field, grounding to establish a stable energetic foundation, and working with protective crystals and intentional boundaries.
