teṣu teṣu hi kṛtyeṣu viniyoktā maheśvaraḥ |
sarvabhūtāni kaunteya kārayatyavaśānyapi || 22 ||

And, O best of men, know that the wealth one obtaineth spontaneously and without cause is said to be a spontaneous acquisition. Whatever is thus obtained by chance, by providential dispensation, spontaneously, of as the result of one's acts is, however, the consequence of the acts of a former life. And God, the Ordainer of the universe, judging according to the acts of former lives, distributeth among men their portions in this world. Whatever acts, good or bad, a person performeth, know that they are the result of God's, arrangements agreeably to the acts of a former life. This body is only the instruments in the hands of God, for doing the acts that are done. Itself, inert, it doth as God urgeth it to do. O son of Kunti, it is the Supreme Lord of all who maketh all creatures do what they do. The creatures themselves are inert. O hero, man, having first settled some purpose in his mind, accomplisheth it, himself working with the aid of his intelligence. We, therefore, say that man is himself the cause (of what he doeth). O bull among men, it is impossible to number the acts of men, for mansions and towns are the result of man's acts. Intelligent men know, by help of their intellect, that oil may be had from sesame, curds from milk, and that food may be cooked by means of igniting fuel. They know also the means for accomplishing all these. And knowing them, they afterwards set themselves, with proper appliances, to accomplish them.
