The second self met beyond the threshold, the enduring being that passes through incarnations and inspires one's karma and destiny from the spiritual world.
The other self is the second self that the soul encounters after crossing the threshold into the spiritual world, perceived within the astral body. Rudolf Steiner taught that this enduring being passes from one earthly life to the next and, working through Inspiration, shapes a person's karma and destiny. It is the spiritual counterpart to the everyday personality, met as if it were another being entirely.
In Steiner's Own Words
How is this other self active? It has just been said that it belongs to the realm of the spirit as a living thought-being among other living thought-beings, whose words are deeds; they accomplish all they do through what we can call Inspiration. The second self acts inspiringly in man's nature. What does it inspire? Our karma, our destiny. Here we discover a mysterious process: whatever our experience, whether painful or joyous, whatever it is that happens in our life, it is inspired by our other self, working from the spiritual world into this one.
What it Means Today
A reader who knows only modern psychology meets a close echo of Steiner's other self in the work of Roberto Assagioli (1888 to 1974), the Italian psychiatrist who founded psychosynthesis and ran the Istituto di Psicosintesi from a villa in Florence. In his 1965 manual Psychosynthesis: A Manual of Principles and Techniques, Assagioli set out an "egg diagram" of the psyche in which the small conscious "I" stands apart from a higher Self, sometimes called the Transpersonal Self, from which the personality is derived. Like Steiner, Assagioli moved through the Theosophical milieu of the early twentieth century, and his higher Self carries the same task Steiner gave the second self: it is the centre that organises a life from above the everyday ego, the source of conscience, vocation, and the sense that one's path has a shape.
The two pictures differ in one decisive way. Assagioli treats the higher Self mainly as a goal of integration, something the personality grows toward across a single lifetime. Steiner places the other self across many lives and gives it a moral edge the clinic rarely names. Thalira synthesis: where psychosynthesis asks the patient to climb toward the higher Self, Steiner reverses the current and says the higher Self is already writing the script, inspiring even the painful accident as your own deed returning, so that meeting it is less self-improvement than recognising the author you have always been.
