Changes

In Hathayoga ...Nature-power, coiled up with all its secret forces asleep in the lowest nervous plexus of the earth-being,—for only so much escapes into waking action in our normal operations as is sufficient for the limited uses of human life,—rises awakened through centre after centre and awakens, too, in its ascent and passage the forces of each successive nodus of our being, the nervous life, the heart of emotion and ordinary mentality, the speech, sight, will, the higher knowledge, till through and above the brain it meets with and it becomes one with the divine consciousness.

…For the methods of the integral Yoga must be mainly spiritual, and dependence on physical methods or fixed psychic or psycho-physical processes on a large scale would be the substitution of a lower for a higher action.

...then followed an era of the development of philosophies and Yoga processes which more and more used the emotional and aesthetic being as the means of spiritual realisation ….We may say therefore that the universal Consciousness after its descent into Matter has conducted the evolution there along two lines, one of ascent to the discovery of the self and spirit, the other of descent through the already evolved levels of mind, life and body so as to bring down the spiritual consciousness into these also and to fulfil thereby some secret intention in the creation of the material universe. Our Yoga is in its principle a taking up and summarising and completing of this process, an endeavour to rise to the highest possible supramental level and bring down its consciousness and powers into mind, life and body.

This energy will not be in its essence an outward, physical or muscular strength, but will be of the nature, first, of an unbounded life-power or pranic force, secondly, sustaining and using this pranic energy, a superior or supreme will-power acting in the body. ...when we go higher, the relation is gradually reversed; it is then able to act in its own power or handle the rest only as a subordinate instrumentation.

...In our Yoga it is not a specialised process, but a spontaneous uprush of the whole lower consciousness sometimes in currents or waves, sometimes in a less concrete motion, and on the other side a descent of the Divine Consciousness and its Force into the body. This descent is felt as a pouring in of calm and peace, of force and power, of light, of joy and ecstasy, of pure wideness and freedom and knowledge, of a Divine Being or a Presence—sometimes one of these, sometimes several of them or all together.

...Once this descent becomes habitual, the Divine Force, the Power of the Mother begins to work, no longer from above only or from behind the veil, but consciously in the Adhara itself, and deals with its difficulties and possibilities and carries on the Yoga. <ref>
