In plain words
So,
All the religions together taught only the good; know this and move through life with understanding. When the minds are good, which religion is bad? Listen, heroic son of Bhārata.
We must recognise that whatever the religions teach, it is for the welfare of all together, not for the welfare of one person. In this very body, made up of filth, urine, foul smells, flesh and blood, the divine and splendid Ātma principle shines. It does not diminish through the body's weakness. It does not grow through the body's strength. The principle that neither grows nor diminishes is the Ātma principle itself. It is ever pure. It is precious. It is strong. In no circumstance does its worth diminish in the least.
If a big diamond is found in a dung heap, its value does not change, its brilliance does not go. If a fine pumpkin ripens on a hedge, its taste does not change, nor does its flavour go. If a hen hatches the egg of a fine peacock, its colour does not change, nor do its markings go.
Though the body is full of many impurities, within it the Ātma principle, spotless, unmoving and selfless, goes on shining always. What does it mean, then, that people of all religions seek strength and contentment for this body? The root cause is the faith that the body is God's temple.
So it is man's chief duty not to neglect this sacred body or treat it carelessly, but to set it on the right path with due care and carry out its duties and actions. But people who cannot recognise this truth wear the body down with many vows, nōmus and fasts. By that we cannot recognise the Ātma principle, the eternal Satya.
If you beat the top of the anthill, will the snake die? If you punish your body, will sensual pleasures cease? If you merely give up hunger and thirst, will you become a knower of the Ātma? If you do not know who you are, will you know the Jñāna of the principle?
