Letters of Sri Aurobindo
13. Opposition of the Hostile Forces
This state which tries to come upon you and seize is not
part of your true self, but a foreign influence. To yield to it and to express
it would therefore be not sincerity, but the expression of 
something false to your true being, something that will grow more and more
foreign to you as you progress. Always reject it, when it comes, even if you
feel strongly its touch; open in your mind and soul to the Mother, keep your
will and faith and you will find it receding. Even if it returns obstinately, be
equally and more obstinate against it, firm in rejection – that will discourage
and wear it out and finally it will grow weak, a shadow of itself and disappear.
Be true to your true self always – that is the real
sincerity. Persist and conquer.
