A unique prayer the child from him received

Sri Aurobindo wrote the following to be used by Mridu-di as her prayer:
"I pray to be purified from self-will and self-assertion so that I may become docile and obedient to the Mother and a fit instrument of her work, surrendered and guided by her grace in all I do.
  November 5th, 1942"

This particular prayer that Mridu-di received was made compulsory for all the students at the Sri Aurobindo Ashram in those days. Every day before starting school, we had to recite the morning prayer, standing up with folded hands.
