Letters of Sri Aurobindo
Volume IV - Part 3
There is always more chance of inertia at night because of the large part taken by the subconscient in sleep – but, apart from that, there should be a reaction (internal) against the rising of inertia. A quietness in the cells of the body, even a sense of immobility (so that the body seems to be moved rather than to move) is a different thing and easily distinguishable from the inertia. The downflow of peace usually brings much of the static Brahman into the consciousness down to the physical, so that one feels the Upanishadic “unmoving it moves”.
