Letters of Sri Aurobindo
Volume IV - Part 3
It is the last reaction of the physical consciousness [feeling dull,weak, confused] 
that must be got rid of – in its place there must be at such times peace constant so that you do not get restless or feel troubled. It is not possible to be always in the best condition of consciousness or sadhana – there are times when the physical needs to be merely quiet, the aspiration becomes quiescent, there is no sense of the Divine, no forward movement. Properly taken, these periods become periods of rest and assimilation but for that the consciousness must learn to be quiet, not to be troubled or thrown back into a bad or uneasy condition – it must remain at repose until the movement is resumed in a quiet peace. Or at least the greater part of the consciousness must feel like that – not even in these periods dull, weak or confused. This feeling seems to be gaining on you, but the physical consciousness or at least a part of it is still uneasy during such intervals. It must go on receiving more of the light and peace till this can no longer happen.
