Instead of working for yourself work for the sake of God. Know that all work you have to do is Sri Ramakrishna’s and Swami Vivekananda’s. If you can work with this idea, your work will not bind you. On the other hand, it will improve you in every way – spiritually, morally, intellectually, and also physically.
(p.235, Eternal Companion, Swami Brahmananda’s words on 12 Feb,1921 at Varanasi.)
