Why should we consciously cultivate our thoughts to be pure and noble and remove other thoughts? Bhagawan reminds us by citing some fundamental truths.

Don’t criticise or condemn others. If you deceive your friends, they, in turn, will cheat you. If you disobey your parents, your children will pay you back in the same coin. If you hurt others, they will hurt you in retaliation. Reaction, resound and reflection are inherent in man’s mind. Hence, you should discerningly follow the maxim: “Hurt never; help ever”. There are some sinful persons who cavil not only at other men but even against God. This seems to be their very nature, although God never harms anyone at any time. In this context, the lowest category of people is those who take sadistic pleasure in hurting other people without any provocation whatsoever. They may be compared to the moths, whose nature is to damage all clothes indiscriminately, whether it is a valuable saree costing one thousand rupees, or whether it is a worthless, soiled rag in the kitchen. This highly despicable tendency on the part of some persons to harm others is traceable to their bad thoughts. We try to dispel foul odours from our living rooms and toilets by using substances like air-fresheners, incense sticks, and other deodorants. Similarly, we should try to counteract our bad thoughts with good ones.
