SB 10.24.13 — Lord Kṛṣṇa said: It is by the force of karma that a living entity takes birth, and it is by karma alone that he meets his destruction. His happiness, distress, fear and sense of security all arise as the effects of karma.
SB 10.24.14 — Even if there is some supreme controller who awards all others the results of their activities, He must also depend upon a performer’s engaging in activity. After all, there is no question of being the bestower of fruitive results unless fruitive activities have actually been performed.
SB 10.24.15 — Living beings in this world are forced to experience the consequences of their own particular previous work. Since Lord Indra cannot in any way change the destiny of human beings, which is born of their own nature, why should people worship him?
SB 10.24.16 — Every individual is under the control of his own conditioned nature, and thus he must follow that nature. This entire universe, with all its demigods, demons and human beings, is based on the conditioned nature of the living entities.
SB 10.24.17 — Because it is karma that causes the conditioned living entity to accept and then give up different high- and low-grade material bodies, this karma is his enemy, friend and neutral witness, his spiritual master and controlling lord.
SB 10.24.18 — Therefore one should seriously worship work itself. A person should remain in the position corresponding to his nature and should perform his own duty. Indeed, that by which we may live nicely is really our worshipable deity.
