This prayer reveals to us the sincerity of teaching.
January 12, 1914
A TEACHING can be profitable only if it is perfectly sincere, that is to say, if it is lived at the time when it is imparted, and words often repeated, thoughts often expressed can no longer be sincere.
The text above is quoted from the Third Edition, 1954 (translation by Rishabhchand Samsukha)
