Volume III - Part 4
It was certainly an experience and as X very accurately described it an experience of great value, a psychic experience par excellence. A feeling of velvety softness within – an ineffable plasticity within is a psychic experience and can be nothing else. It means a modification of the substance of the consciousness especially in the vital emotional part, and such a modification prolonged or repeated till it became permanent would mean a great step in what I call the psychic transformation of the being. It is just these modifications in the inner substance that make transformation possible. Farther, it was a modification that made a beginning of knowledge possible – for by knowledge 
we mean in Yoga not thought or ideas about spiritual things but psychic understanding from within and spiritual illumination from above. Therefore the first result was this feeling “that there was no ignominy in not understanding it, that the true understanding would come only when one realised that one was completely impotent”. This was itself a beginning of true understanding, a psychic understanding, something felt within which sheds a light or brings up a spiritual truth that mere thinking would not have given, also a truth that is effective bringing both the enlightenment and solace you needed – for what the psychic being brings with it always is light and happiness, an inner understanding and relief and solace.
Another very promising aspect of this experience is that it came as an immediate response to an appeal to the Divine. You asked for the understanding and the way out and at once Krishna showed you both – the way out was the change of the consciousness within, the plasticity which makes the knowledge possible and also the understanding of the condition of mind and vital in which the true knowledge or power of knowledge could come. For the inner knowledge comes from within and above (whether from the Divine in the heart or from the Self above) and for it to come the pride of the mind and vital in the surface mental ideas and their insistence on them must go. One must know that one is ignorant before one can begin to know. This shows that I was not wrong in pressing for the psychic opening as the only way out. For as the psychic opens, such responses and much more also become common and the inner change also proceeds by which they are made possible.
