In plain words
We must recognise that our returns come according to our deeds. The chief beliefs of the Indians are three. The fruit of karma is one. We cannot escape what we have done. It must be lived through: that is the doctrine of karma.
The second is the principle of the Avatāra. Avatāra means to believe in God. It is a truth that humanness has come forth only from God. Man is not simply one with this shape. Human birth is truly hard to win. Jantūnāṃ narajanma durlabham. Why is it hard to win? If, like the beasts, birds and animals, we merely roam, eat, enjoy ourselves, sleep in comfort and live in pleasure and plenty, then we too may as well be like the beasts and birds, may we not? Then what is the inner meaning of saying that human birth is hard to win? The power to enquire into the eternal and the passing is in man alone. The divine power that makes us aware of past, future and present is in man alone. So people have long regarded humanness as something hard to win. Now, man may think of the future. Man may brood over what has passed. He may live through what is happening. But this too is a path contrary to man. We must not brood over what has passed. The reason is that what has passed we are living through even now. However much we brood, what has passed will not come forward even by one moment. There is no need to worry about the future. The reason: there is no surety at all that I will be here until tomorrow. Why should we worry about the future? While we think of tomorrow, we may go today itself. So it said to keep the present in mind. That is, we called this the present, Present. But in God's sight this is not an ordinary Present. It is omni Present. Why did we call it omni Present? The result of what has passed is in this present. The fruit of what we are doing in this Present, what is to come, is also in this Present alone. What we ate comes up now as a belch. What we are about to eat now will come up as a belch tomorrow. For the belch to come and the belch now coming, the Present is what matters. What has passed and what is to come are in the Present alone. But for want of such deep, such long thought, man keeps brooding over Past, Present and Future: over what has passed, what is to come, and the present. These, past, future and present, do not exist in divinity; it is wholly contrary to … .
A small example. "Swami knows what is to come, does He not? He knows how the future will be, does He not; did Swami not know He would fall in this bathroom?" Some people have such a thought.
