So to begin with knowledge, Kṛṣṇa recommends amānitvam, humility. Because the real disease of material life is that he is not humble. He is always proud. Little possession. Svalpa-mātrena. Just like the big fish in the ocean. They are deep within the water and if you find out a small lake, little water, you'll find small fishes (makes sound) they're doing there. So there is no depth of knowledge. Simply they're perplexed. Therefore this education should be given, how to become humble. Śiṣyas te 'haṁ śādhi māṁ tvaṁ prapannam (BG 2.7). Tad viddhi praṇipātena paripraśnena sevayā (BG 4.34). Paripraśnena sevayā. One has to learn by service, by praṇipāta, praṇipāta means surrender. There is no surrender. Nobody is prepared to surrender. "Oh, why shall I surrender? I know everything." Puffed-up unnecessarily. Therefore Kṛṣṇa says the material disease is that rajas-tamo-bhāvāḥ. Tadā rajas-tamo-bhāvāḥ kāma-lobhādayaś (ca ye) (SB 1.2.19). Rajas-tamo-bhāvāḥ means, rajo-guṇa, kāma and lobha. Ignorance.
Everyone is thinking if I become greedy, I shall get more. That is not possible. You cannot get a farthing more than what you are destined. But it is ignorance. He's thinking by simply struggling hard I'll get more. The śāstra says, "No, don't do it. So far your material condition is concerned, it is already destined with your body. You have got a certain type of body and according to that body you'll get certain amount of pleasure and pains, that is already destined." This is called adṛṣṭa, daiva. Your main business is if you want to make success, your life, then save time for advancing in Kṛṣṇa consciousness. That is proper utilization of life. That does not depend on destiny. That you can do. That you can do. So far other things are.
