by Swami Sivananda
He was aware, during this first period of illumination and during the months which followed, of a number of physiological changes within himself. The most striking was what seemed a rearrangement of molecule structure in his brain or the opening up of new cell-territory there. Ceaselessly, day and night, he was conscious of this work going on. It seemed as though a kind of electrical drill was boring out new cellular thought-channels. This phenomenon is strong proof of Bucke's theory that cosmic consciousness is a natural faculty of man, for it gives evidence that the brain-cells which are connected with this faculty are already present in man, although inactive or non-functioning in the majority of human beings at the present time.
Another important change was felt in his spinal column. The whole spine seemed turned into iron for several months, so that, when he sat to meditate on God, he felt anchored forever, able to sit in one place eternally without motion or consciousness of any bodily function. At times an influx of superhuman strength invaded him and he felt that he was carrying the whole universe on his shoulders. The elixir of life, the nectar of immortality, he felt flowing in his veins as an actual, tangible force. It seemed like a quicksilver or a sort of electrical, fluid light throughout his body.
