It is necessary for the worker to sit in solitude daily in the mornings and night and probe his mind. With a discerning intellect he must find out whether any unworthy thought had entered his mind. If so, he should resolve to throw them out, and become purer from the next day. He should detach his mind from unholy associations and make it immersed in thoughts concerning the chosen mission of his life. He will, in course of time, find that his mind has become less prone to evil propensities and more attuned to the noble impulses.
– Shri Guruji Golwalkar
