Letters of Sri Aurobindo
Volume III - Part 4
The experiences you describe are coherent with each other and very clearly explicable. The first shows that some part of your 
mind was open and this aided by an opening in the psychic enabled you to ascend into the regions above, the ranges of the liberated spiritual mind with the infinite path of the spirit leading to the highest realisation. But the rest of the nature was not ready. The straining to recover the experience was not the right thing to do then; what should have been done was the aspiration for the purification and preparation of the nature, the permanent psychic opening and the increase of the higher spiritual opening above till there could be a total release of the being. The vehemence of the action of the forces was due to the resistance and the breaking of the knots in the head and different parts of the nature was their working for the release. The “electricity” passing through the spinal column was the passage of the Force making its way down through the centres. Obviously it is the dark resisting force of the vital, the desire nature, that rises up and clouds all up to the heart. On the other hand the flow from above and the silence it creates is a sign of the opening above being still there; for the silence, the quietude of the nature is a touch from above and very necessary for purification and release. What is lacking is the full opening of the psychic being behind the heart – for that could liberate the heart from the dark force and make possible a cleaning of the rest by a quiet and steady rather than a vehement working attended by chaotic action and struggle. When there is an opening in the spiritual mind but not a sufficient psychic change, there is or can be this kind of vehement force-action and resistance; when the psychic opens, then it acts on the whole nature, mind, vital, physical, governing them from within, to transform themselves and become ready for the complete spiritual opening and spiritual consciousness. Devotion and a more and more complete inner consecration are the best way to open the psychic.
