He who gives spiritual knowledge, saves the soul from many end many a birth. He who gives secular knowledge opens the eyes of human beings to wards spiritual knowledge, and far below these rank all other gifts, even the saving of life. Therefore it is necessary that you learn this and note that all other kinds of work are of much less value than that of imparting spiritual knowledge. The highest and greatest help is that given in the dissemination of spiritual knowledge. There is an eternal fountain of spirituality in our scriptures, and nowhere on earth, except in this land of renunciation, do we find such noble examples of practical spirituality.
