Letters of Sri Aurobindo
Volume IV - Part 4
There is no reason for despondency; when one has progressed as far as you did, that is, so far as to feel and maintain the calm and have so much of the psychic discrimination and the psychic feeling, one has no right to despair of one’s spiritual future. You could not yet carry out the discrimination into an entire psychic change, because a large part of the outer physical consciousness still took some pleasure in old movements and therefore their roots remained alive in the subconscient. When you were off your guard the whole thing rose up and there was a temporary and violent lapse. But this does not mean that the nature is not 
changeable. Only the calm inner conscious poise, the psychic discrimination and above all a will to change, stronger and steadier than before, must be so established that no uprising or invasion will be able to cloud even partly the discrimination or suspend the will. You saw the truth but this part of the old nature which rose up did not want to acknowledge – it wanted its play and imposed that on you. This time you must insist on a complete truthfulness in the whole being which will refuse to accept any denial of what the psychic discrimination sees or any affirmation or consent anywhere to what it disapproves, spiritual humility and the removal of self-righteousness, self-justification and the wish to impose yourself, the tendency to judge others etc. All these defects you know are in you; to cast them out may take time, but if the will to be true to the inner self in all ways is strong and persistent and vigilant and always calls in the Mother’s force, it can be done sooner than now seems possible.
