Letters of Sri Aurobindo
Volume III - Part 4
That the constant fire of aspiration has to be lit is true; but this fire is the psychic fire and it is lit or burns up and increases as the psychic grows within and for the psychic to grow quietude is needful. That is why we have been working for the psychic to 
grow in you and for the quietude also to grow and that is why we want you to wait on the Mother’s working in full patience and confidence. To be always remembering the Mother and always with the equal unwavering fire within means itself a considerable progress in sadhana and it must be prepared by various means such as the experiences you have been having. Keep steadfast in confidence therefore and all that has to be done will be done.
