Trataka is a yogic concentration practice of steady, unblinking gazing at a single point (most commonly a candle flame). Listed in the Hatha Yoga Pradipika as one of the six shatkarmas (purification techniques), it develops concentration, cleanses the eyes, produces a vivid afterimage for internal meditation, and is traditionally associated with activating the ajna chakra (third eye).
- Trataka is one of the six shatkarmas (purification practices) in the Hatha Yoga Pradipika, classified as both a cleansing technique and a gateway to dharana (concentration), the sixth limb of Patanjali's yoga
- The practice has two phases: bahir trataka (external gazing at the flame with open eyes) and antar trataka (closing the eyes and holding the afterimage internally), developing both external focus and internal visualisation
- Preliminary research shows benefits for sustained attention, memory, and anxiety reduction, though rigorous clinical trials are limited; a 2014 study found six weeks of trataka improved attention and cognitive function in college students
- Practise for no more than 10 minutes per session (beginners start at 2-3 minutes), at arm's length from the flame, in a draft-free room; take a two-week break every two months to prevent eye strain
- People with epilepsy, photosensitive seizure conditions, glaucoma, or retinal conditions should avoid or modify the practice
What Is Trataka?
Trataka (Sanskrit: "to gaze" or "to look steadily") is the practice of fixing the eyes on a single point without blinking until tears flow. It is, in its simplest form, a staring exercise. But within the yogic system, it occupies a unique position: it is the only one of the six shatkarmas (purification practices) that directly develops concentration (dharana), making it both a physical cleansing technique and a mental training.
The most common object of trataka is a candle flame, though classical texts describe numerous alternatives: the tip of the nose, a black dot on white paper, a small image, a crystal, a yantra (geometric diagram), or even a star. The candle flame is favoured because it provides a naturally compelling focal point (the eye is drawn to light), it moves slightly (maintaining engagement without distraction), and it produces a clear afterimage when the eyes close (facilitating internal meditation).
Where most meditation practices ask you to close your eyes and turn attention inward, trataka asks you to keep your eyes open and fix them on an external point. This makes it particularly accessible for people who find closed-eye meditation difficult due to restlessness, drowsiness, or excessive mental activity. The external focus gives the wandering mind something concrete to return to.
Classical Sources: Hatha Yoga Pradipika and the Shat Kriyas
The primary classical reference for trataka is the Hatha Yoga Pradipika (HYP), composed by Swami Svatmarama in the 15th century CE. Chapter 2, verse 31 states:
"Being calm, one should gaze steadily at a small mark until tears are shed. This is called trataka by the gurus."
Verse 32 continues: "Trataka eradicates all eye diseases, fatigue, and sloth, and closes the doorway to these problems. It should be carefully kept secret like a golden casket."
The HYP classifies trataka as the fifth of the six shatkarmas. The complete set of purification practices is:
| Shatkarma | Area Purified | Method |
|---|---|---|
| Neti | Nasal passages | Saline water or thread through the nose |
| Dhauti | Digestive tract | Swallowing cloth, water, or air |
| Nauli | Abdominal organs | Rotational movement of abdominal muscles |
| Basti | Colon | Water enema through yogic technique |
| Kapalabhati | Sinuses, brain | Rapid, forceful exhalations |
| Trataka | Eyes, mind | Steady gazing at a fixed point |
The Gheranda Samhita, another classical Hatha Yoga text, also describes trataka and further categorises it into bahir (external) and antar (internal) practice.
Bahir and Antar Trataka: External and Internal Gazing
A complete trataka session involves two distinct phases:
Bahir Trataka (External Gazing): Gazing at the physical candle flame with open eyes, without blinking, until the eyes water naturally. The tears serve a dual purpose: they cleanse the eyes (the purification aspect) and they signal that the eyes have reached their limit of sustained focus (indicating it is time to close them).
Antar Trataka (Internal Gazing): After closing the eyes, the practitioner holds the afterimage of the flame in the mind's eye. The afterimage typically appears as a complementary colour (the candle flame's yellow-orange produces a blue-violet afterimage). The practitioner focuses on this internal image, keeping it as stable and vivid as possible until it fades.
Antar trataka is the more subtle and ultimately more important phase. It develops the faculty of internal visualisation, what yogic tradition calls the "mind's eye" and what Steiner calls "thinking in images" (Imagination). The ability to hold a vivid, stable internal image is foundational for advanced meditation practices across multiple traditions.
When you close your eyes after bahir trataka, the afterimage typically progresses through several stages: (1) a vivid complementary-colour image of the flame (blue-violet), (2) the image begins to pulse, expand, or shift colours, (3) the image fragments or fades, (4) a diffuse glow or darkness replaces it. The practice is to sustain attention on the image through all stages, observing each change without reacting. With practice, the afterimage becomes clearer, more stable, and lasts longer.
How to Practise Candle Flame Trataka
- Setup: Place a lit candle at eye level when seated, approximately arm's length away (60-90 cm). The room should be dark or dimly lit, and draft-free so the flame remains steady. A flickering flame strains the eyes more than a steady one.
- Posture: Sit in a comfortable position with a straight spine: cross-legged on the floor, on a meditation bench, or in a chair. The key is that your eyes are level with the flame without needing to tilt your head up or down.
- Relaxation: Close your eyes briefly. Take several slow breaths. Relax the face, jaw, and especially the muscles around the eyes. Set an intention for steady, gentle observation.
- Bahir Trataka (External, 3-5 minutes): Open your eyes and fix your gaze on the brightest point of the flame (the tip of the blue inner cone is traditional). Gaze steadily without blinking. When the urge to blink becomes strong, try to maintain the gaze a moment longer. When tears begin to form or the eyes water naturally, close your eyes.
- Antar Trataka (Internal, 2-3 minutes): With eyes closed, observe the afterimage of the flame. It will appear as a coloured spot, often blue or violet. Hold your attention on it gently. When it begins to drift, follow it. When it fades, observe the fading. When it disappears, sit in the stillness that remains.
- Repeat or rest: You may repeat the cycle (open eyes, gaze, close eyes, afterimage) 2-3 times per session. End by rubbing the palms together vigorously and placing the warm palms gently over the closed eyes (palming), allowing the eyes to relax completely.
Trataka with Other Objects
While the candle flame is the most popular trataka object, the classical texts describe several alternatives, each with different qualities:
- Black dot on white paper (bindu): The simplest form. Draw a small black circle (about 1 cm diameter) at eye level. This produces a clear afterimage and removes the safety concerns associated with candle gazing.
- Crystal or gemstone: A clear quartz sphere or a polished stone provides a reflective, light-catching surface that maintains visual interest. Crystal trataka connects the concentration practice to the crystal's traditional symbolic associations.
- Yantra: A geometric diagram (such as the Sri Yantra) provides a complex visual object. The eye can rest on the central point (bindu) while the peripheral vision takes in the geometric structure. Yantra trataka combines concentration with contemplation of sacred geometry.
- Moon: Gazing at the full moon is a traditional trataka practice. The moon provides soft, steady light that does not strain the eyes, and the practice connects the meditator to natural cycles.
- Tip of the nose (nasagra drishti): Looking at the tip of one's own nose. This is both a trataka object and a pranayama/meditation preliminary, mentioned in the Bhagavad Gita (Chapter 6, verse 13).
Trataka and the Third Eye
In yogic anatomy, trataka is closely associated with the ajna chakra, the "third eye" centre located between and slightly above the eyebrows. The ajna chakra is traditionally associated with intuition, inner vision, clarity of thought, and the capacity for what Patanjali's Yoga Sutras call prajna (wisdom born of direct perception).
The mechanism proposed by the yogic tradition is that sustained concentration through trataka draws prana (life force) upward through the sushumna nadi (central channel) to the ajna centre. When sufficient prana accumulates, the faculties associated with ajna begin to activate: heightened intuition, vivid mental imagery, and what yogic texts describe as "the eye of knowledge" (jnana chakshu).
Modern neuroscience does not validate the chakra model directly, but there are interesting parallels. Sustained visual focus activates the prefrontal cortex (associated with executive function and sustained attention), and the internal visualisation phase of antar trataka engages the same brain regions used in mental imagery and creative thinking. The "third eye" may be a traditional way of describing enhanced executive and attentional capacities that arise from systematic concentration training.
Trataka as Concentration Training
Within Patanjali's eight-limbed yoga system, trataka functions as a bridge between pratyahara (sense withdrawal, the fifth limb) and dharana (concentration, the sixth limb). By fixing the gaze on a single object, the practitioner withdraws attention from all other sensory input (pratyahara) and simultaneously develops one-pointed focus (dharana).
This makes trataka particularly useful for people who struggle with sitting meditation. In Vipassana or samatha practice, the meditation object (breath, body sensations) is subtle and internal. The untrained mind has difficulty staying with such subtle objects. A candle flame is vivid, external, and visually compelling, making it easier for beginners to maintain focus. Once concentration is developed through trataka, it can be transferred to subtler meditation objects.
This is why the Hatha Yoga tradition positions the shatkarmas (including trataka) as preparations for pranayama and meditation, not as ends in themselves. They purify and prepare the body and mind so that deeper practices become possible.
Visual Phenomena During Practice
Several visual phenomena are commonly experienced during trataka practice:
- Colour changes: The flame may appear to shift colours, or a halo of colour may appear around it. This is caused by retinal fatigue in the cone cells responsible for colour perception.
- Peripheral vision changes: The area around the flame may darken, appear to pulse, or seem to dissolve. This is a normal consequence of sustained foveal focus: the brain de-prioritises peripheral visual processing.
- Size distortions: The flame may appear to grow larger, shrink, or vibrate. This is related to accommodation fatigue (the eye's focusing mechanism) and microsaccade suppression.
- Afterimage phenomena: The afterimage during antar trataka may appear as a vivid coloured disc, a pulsing star, or a complex pattern. It may move, transform, or remain stable depending on the practitioner's concentration.
- "Tunnel vision": A narrowing of the visual field to just the flame, with everything else fading. This is a natural consequence of sustained attention and is related to the brain's selective attention mechanisms.
These phenomena are entirely normal and are explained by well-understood visual neuroscience. They are not mystical experiences, though the yogic tradition sometimes interprets them as signs of energetic changes at the ajna chakra. The practical instruction is the same regardless of interpretation: observe the phenomena without reacting to them, and maintain steady attention.
What the Research Shows
Research on trataka specifically is limited but suggestive:
- Mallick and Kulkarni (2014) found that six weeks of daily trataka practice improved selective attention and cognitive function in college students, as measured by the Stroop test and Trail Making Test.
- A small study in the International Journal of Yoga found that trataka combined with pranayama reduced anxiety scores in participants compared to a control group.
- Research on fixation stability (a related concept in vision science) shows that sustained visual focus activates the dorsolateral prefrontal cortex and anterior cingulate cortex, brain regions critical for executive attention and self-regulation.
- The afterimage component of antar trataka engages the same neural substrates as deliberate mental imagery, a capacity linked to creative problem-solving, memory consolidation, and motor skill acquisition.
Most trataka studies are small, lack rigorous controls, and are published in journals with limited impact. The claims about eye disease treatment, "eradicating sloth," and third eye activation remain within the domain of yogic tradition rather than evidence-based medicine. Trataka is best understood as a concentration training technique with preliminary evidence of cognitive benefits, not as a medical treatment.
Steiner's Parallel Exercises for the Will
Rudolf Steiner, in How to Know Higher Worlds (1904) and related lecture cycles, described concentration exercises that parallel trataka in several ways. Steiner's basic concentration exercise involves selecting a simple object (a pin, a pencil, a button) and holding it in the mind with sustained, focused attention, observing every detail while excluding all other thoughts.
The parallel to trataka is structural: both practices train the will through sustained, one-pointed attention on a single object. Steiner described this faculty as "thinking-will" or "will-permeated thinking," the capacity to direct attention deliberately rather than being carried along by the stream of association. He considered this capacity foundational for what he called "Imagination" (the first stage of higher knowledge), which is the ability to perceive supersensible realities through thinking freed from sensory dependence.
The antar trataka phase (holding the afterimage with the mind's eye) corresponds closely to what Steiner describes as the transition from sensory perception to imaginative perception: the object is no longer physically present, but the mind holds its image with the same clarity and stability as if it were. This trained faculty of vivid, willed mental imagery is central to both the yogic and Hermetic contemplative traditions.
The Hermetic Synthesis course examines how concentration practices like trataka and Steiner's exercises develop the same inner capacities through different cultural frameworks.
Safety and Contraindications
- Duration: Limit sessions to 10 minutes maximum (beginners: 2-3 minutes). Take a two-week break every two months of regular practice.
- Distance: Maintain arm's length (60-90 cm) from the flame. Too close increases eye strain and heat exposure.
- Room conditions: Draft-free room with steady flame. A flickering flame causes more eye strain than a steady one.
- Epilepsy: Do not practise candle flame trataka if you have epilepsy or photosensitive seizure disorders. Use a black dot on white paper instead.
- Eye conditions: Consult an ophthalmologist before practising if you have glaucoma, retinal conditions, cataracts, or have had recent eye surgery.
- Contact lenses: Remove contact lenses before practice. The reduced blinking rate during trataka can cause dryness and discomfort with lenses in.
- Palming: Always end a session with palming (rubbing palms together and placing warm palms over closed eyes) to relax the eye muscles and return to normal visual function.
Common Mistakes
- Forcing the eyes open: Trataka should involve gentle steadiness, not muscular strain. If you are grimacing or tensing the face, you are trying too hard. Relax the face and let the gaze be soft but steady.
- Practising too long: Longer is not better. Ten minutes of relaxed gazing produces more benefit than 30 minutes of strained effort.
- Ignoring the antar phase: The internal visualisation phase (antar trataka) is at least as important as the external gazing. Do not skip it.
- Chasing visual phenomena: Colour changes, size distortions, and tunnel effects are normal. Do not interpret them as spiritual experiences or try to intensify them. They are optical phenomena, interesting but not the point of the practice.
- Practising in a drafty room: A flickering flame causes the eyes to constantly readjust, producing strain rather than steadiness.
Trataka is, at its core, the simplest of all meditation practices: look at something without looking away. But in that simplicity lies a profound training. The ability to hold your gaze steady, to resist the eye's constant urge to dart and scan and blink, develops a quality of will and attention that extends far beyond the meditation cushion. The steady gaze, once cultivated, becomes a steady mind. And a steady mind is the foundation for every other contemplative practice, whether Buddhist, yogic, Hermetic, or any other tradition that asks you to look clearly at what is actually there.

Frequently Asked Questions
What is trataka meditation?
Trataka is a yogic concentration practice involving steady, unblinking gazing at a single point, most commonly a candle flame. Listed in the Hatha Yoga Pradipika as one of the six shatkarmas, it develops concentration, cleanses the eyes, and is traditionally believed to activate the third eye (ajna chakra).
How long should I practise trataka?
Beginners should start with 2-3 minutes, gradually increasing to 10 minutes over several weeks. Do not exceed 10 minutes per session. Take a two-week break every two months of regular practice.
Is candle gazing safe for the eyes?
Generally safe when practised correctly: limited duration, adequate distance, steady flame, and periodic breaks. People with eye conditions should consult their ophthalmologist.
What is the difference between bahir and antar trataka?
Bahir trataka is external gazing at a physical object. Antar trataka is closing the eyes and holding the afterimage internally. A complete session includes both phases.
Can I practise trataka without a candle?
Yes. Traditional alternatives include a black dot on white paper, a crystal, a yantra, the moon, or the tip of the nose. The candle is most popular because it produces a clear afterimage.
What is the connection between trataka and the third eye?
Trataka is traditionally associated with the ajna chakra (third eye). Sustained concentration is believed to draw prana to this centre, activating intuition and inner vision. Modern neuroscience notes that sustained visual focus affects prefrontal cortex activity.
Does trataka help with concentration and ADHD?
Preliminary research suggests benefits for sustained attention. A 2014 study found six weeks of trataka improved attention in college students. However, no rigorous clinical trials have tested it specifically for ADHD.
What are the shat kriyas?
The six purification techniques in the Hatha Yoga Pradipika: neti, dhauti, nauli, basti, kapalabhati, and trataka. They prepare the body and mind for pranayama and meditation.
Can trataka cause hallucinations?
Prolonged gazing produces visual phenomena (colour shifts, size distortions, vivid afterimages) that are normal optical effects, not hallucinations. If disturbing, reduce practice duration.
Who should not practise trataka?
People with epilepsy, photosensitive seizure conditions, glaucoma, retinal conditions, or recent eye surgery. People with severe anxiety or psychotic conditions should approach cautiously.
