The practice of this Yoga is double—one side is of an ascent of the consciousness to the higher planes, the other is of a descent of the power of the higher planes into the earth consciousness so as to drive out the Power of darkness and ignorance and transform the nature.

Yoga means union with the Divine—a union either transcendental (above the universe) or cosmic (universal) or individual or, as in our Yoga, all three together. Or it means getting into a consciousness in which one is no longer limited by the small ego, personal mind, personal vital and body but is in union with the supreme Self or with the universal (cosmic) consciousness or with some deeper consciousness within in which one is aware of one’s own soul, one’s own inner being and of the real truth of existence. In the Yogic consciousness one is not only aware of things, but of forces, not only of forces but of the conscious being behind the forces. One is aware of all this not only in oneself but in the universe.

There is a double movement in the sadhana—the Divine Consciousness, Power, Light, Peace descending into all the body, the consciousness from all parts of the body rising upwards to meet the Divine Consciousness above—the descent and the ascent.
Sri Aurobindo – Letters on Yoga: CWSA, Vol. 30, pp415-16
All the consciousness in the human being who is the mental embodied in living matter has to rise so as to meet the higher consciousness; the higher consciousness has also to descend into mind, into life, into matter. In that way the barriers will be removed and the higher consciousness will be able to take up the whole lower nature and transform it by the power of the supermind.
Sri Aurobindo – Letters on Yoga: CWSA, Vol. 30, p416
The sadhana is based on the fact that a descent of Forces from the higher planes and an ascent of the lower consciousness to the higher planes is the means of transformation of the lower nature—although naturally it takes time and the complete transformation can only come by the supramental descent. Your experiences here are forms of the widening experiences of this process.
Sri Aurobindo – Letters on Yoga: CWSA, Vol. 30, p416
The earth is a material field of evolution. Mind and life, supermind, Sachchidananda are in principle involved there in the earth consciousness, but only matter is at first organised; then life descends from the life plane and gives shape and organisation and activity to the life principle in matter, creates the plant and animal; then mind descends from the mind plane, creating man. Now supermind is to descend so as to create a supramental race.
Sri Aurobindo – Letters on Yoga: CWSA, Vol. 30, p416
There are two movements—one an ascension of the lower consciousness to meet the higher, the other the descent of the higher consciousness into the lower. What you first experienced was an uprush of the lower consciousness from all parts so strong as to break the lid of the inner mind—that was the splitting of the skull—and to enable the joining of the two consciousnesses above to be complete. The result was a descent. Usually the first thing that descends from the higher consciousness is its deep and entire peace—the second is the Light, here the white light of the Mother. When the higher consciousness descends or is intensely felt, there is very usually an opening of the limited personal being into the cosmic consciousness—one feels a wide and infinite being which alone exists, the identification with the body and even the sense of the body disappears, the limited personal consciousness is lost in the Cosmic Existence. You had all this first in the impersonal way, but after the burning up of the psychic fire, you felt the Personal wideness, the cosmic consciousness of the Divine Mother and received her blessing.

If your consciousness rises above the head, that means that it goes beyond the ordinary mind to the centre above which receives the higher consciousness or else towards the ascending levels of the higher consciousness itself. The first result is the silence and peace of the Self which is the basis of the higher consciousness; this may afterwards descend into the lower levels, into the very body. Light also can descend and Force. The navel and the centres below it are those of the vital and the physical; something of the higher Force may have descended there.
Sri Aurobindo – Letters on Yoga: CWSA, Vol. 30, p417
There is a force which accompanies the growth of the new consciousness and at once grows with it and helps it to come about and to perfect itself. This force is the Yoga shakti. It is here asleep and coiled up in all the centres of our inner being (chakras) and is at the base what is called in the Tantras the Kundalini shakti. But it is also above us, above our head as the Divine Force—not there coiled up, involved, asleep, but awake, scient, potent, extended and wide; it is there waiting for manifestation and to this Force we have to open ourselves—to the power of the Mother. In the mind it manifests itself as a divine mind-force or a universal mind-force and it can do everything that the personal mind cannot do; it is then the Yogic mind-force. When it manifests and works in the vital or physical in the same way, it is then apparent as a Yogic life-force or a Yogic body-force. It can awake in all these forms, bursting outwards and upwards, extending itself into wideness from below; or it can descend and become there a definite power for things; it can pour downwards into the body, working, establishing its reign, extending into wideness from above, link the lowest in us with the highest above us, release the individual into a cosmic universality or into absoluteness and transcendence.
Sri Aurobindo – Letters on Yoga: CWSA, Vol. 30, p422
There is a Yoga Shakti lying coiled or asleep in the inner body, not active. When one does Yoga, this force uncoils itself and rises upward to meet the Divine Consciousness and Force that are waiting above us. When this happens, when the awakened Yoga Shakti arises, it is often felt like a snake uncoiling and standing up straight and lifting itself more and more upwards. When it meets the Divine Consciousness above, then the force of the Divine Consciousness can more easily descend into the body and be felt working there to change the nature.
Sri Aurobindo – Letters on Yoga: CWSA, Vol. 30, p421
There are in fact two systems simultaneously active in the organisation of the being and its parts;—one is concentric, a series of rings or sheaths with the psychic at the centre; another is vertical, an ascension and descent, like a flight of steps, a series of superimposed planes with the Supermind-Overmind as the crucial nodus of the transition beyond the human into the Divine. For this transition, if it is to be at the same time a transformation, there is only one way, one path. First, there must be a conversion inwards, a going within to find the inmost psychic being and bring it out to the front, disclosing at the same time the inner mind, inner vital, inner physical parts of the nature. Next, there must be an ascension, a series of conversions upwards and a turning down to convert the lower parts. When one has made the inward conversion, one psychicises the whole lower nature so as to make it ready for the divine change. Going upwards, one passes beyond the human mind and at each stage of the ascent there is a conversion into a new consciousness and an infusion of this new consciousness into the whole of the nature. Thus rising beyond intellect through illuminated higher mind to the intuitive consciousness, we begin to look at everything not from the intellect range or through intellect as an instrument, but from a greater intuitive height and through an intuitivised will, feeling, emotion, sensation and physical contact. So, proceeding from intuition to a greater overmind height, there is a new conversion and we look at and experience everything from the overmind consciousness and through a mind, heart, vital and body surcharged with the overmind thought, sight, will, feeling, sensation, play of force and contact. But the last conversion is the supramental, for once there, once the nature is supramentalised, we are beyond the Ignorance and conversion of consciousness is no longer needed, though a farther divine progression, even an infinite development is still possible.
