PURITY WHICH IS THE GOAL OF WORK IS REALISABLE ONLY THROUGH DOING GOOD TO OTHERS

This help is called religion; the rest is irreligion. This help is work; the rest is evil-doing — I see nothing else. Other kinds of work, for example, the Vaidika or the Tântrika, may produce results; but resorting to them is simply waste of life, for that purity which is the goal of work is realisable only through doing good to others.
