Volume III - Part 4
The Power above the head is of course the Mother’s – it is the power of the Higher Consciousness which is preparing its way of descent. This Higher Consciousness carrying in it a sense of wide and boundless existence, light, power, peace, Ananda etc. is always there above the head and when something of the spiritual Force comes down to work upon the nature, it is from there that it comes. But nothing like the full descent of the peace, bliss etc. can come so long as the being is not ready. Very usually the first preparation is to work on the mind and vital and physical nature in such a way that the soul, the psychic being can have a chance of manifesting itself and influencing the rest of the nature; for that purpose all the main darknesses in the mind and vital have to be combated and thrown out and the physical also prepared in an initial way so that the descent may be possible. This is what has been done so long in you. It has to be made stronger and more complete; but sufficient has been done for it to be possible to prepare the descent of the higher consciousness. There are two 
things that take place; an ascent of one’s consciousness to the higher levels in and above the head, and a descent of the higher consciousness which is above into one’s mind, vital and body. How it is done or by what stages or how long it will take varies with each person. But this new consciousness is very different from the ordinary one and many things happen in its coming which would not happen to the mind and might seem strange to it – e.g. the dissolution of the ego and the opening into a wider self or spirit not limited by the body, to which the body is only a small instrument and nothing more. One must therefore dismiss all fear of new things and accept with calm and confidence each field of new experience, relying on the Divine Mother-Force for guidance and support and protection throughout the change.
