Mahabharata 10.2.6

10.2.6

utthānaṃ cāpyadaivasya hyanutthānasya daivatam |
vyarthaṃ bhavati sarvatra pūrvaṃ kastatra niścayaḥ || 6 ||

Kripa said, "We have heard all that thou hast said, O puissant one! Listen, however, to a few words of mine, O mighty armed one! All men are subjected to and governed by these two forces, Destiny and Exertion. There is nothing higher than these two. Our acts do not become successful in consequence of destiny alone, nor of exertion alone, O best of men! Success springs from the union of the two. All purposes, high and low, are dependent on a union of those two. In the whole world, it is through these two that men are seen to act as also to abstain. What result is produced by the clouds pouring upon a mountain? What results are not produced by them pouring upon a cultivated field? Exertion, where destiny is not auspicious, and absence of exertion where destiny is auspicious, both these are fruitless! What I have said before (about the union of the two) is the truth. If the rains properly moisten a well-tilled soil, the seed produces great results. Human success is of this nature.
