"So without being Kṛṣṇa conscious, there is no end of sense gratification. Nobody knows. But Kṛṣṇa conscious person, they are satisfied. Even still in India, you'll find this satisfaction by Kṛṣṇa consciousness. A poor man, practically very meager income, but he's satisfied. He's satisfied in this way: he thinks, 'Kṛṣṇa has given me this much. I must be satisfied. Kṛṣṇa has given me this much. Why shall I...?' And that is also recommendation of the śāstra, that tasyaiva hetoḥ prayateta kovido na labhyate yad bhramatām upary adhaḥ (SB 1.5.18). We should not waste our time for improving our economic position. That is already settled up.
So 'Whatever Kṛṣṇa will do, that is all right. Let me utilize my valuable time of this human form of life in chanting Hare Kṛṣṇa.' People will not agree to this. But actually, if anyone wants peace of the mind, yenātmā suprasīdati, then this process should be adopted. This is practical also. There are many saintly persons; they do not try where to go, where to take money or where to eat. They're busy in Kṛṣṇa consciousness. 'If Kṛṣṇa sends some food, I shall eat. Otherwise, it doesn't matter. I shall starve.' They have got that determination, strict. They do not go anywhere, but Kṛṣṇa sends him everything.
Just like Bilvamaṅgala. He was not going anywhere. He was living in Vṛndāvana. Kṛṣṇa personally was coming to give him some milk. He became blind; he could not see. So Kṛṣṇa would come just like a boy. 'Bilvamaṅgala, I think you are hungry. Will you take some milk?' Oh, he was very glad. 'All right, You give me a little milk.' Next day He will come. Then he would ask, 'Who is this boy? I cannot see. He comes and gives me milk daily.'
Yoga-kṣemaṁ vahāmy aham (BG 9.22). In the Bhagavad-gītā it is said that 'Unto the devotee who is completely dependent upon Me, I carry personally whatever he needs.' Eko bahūnāṁ yo vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13). That one person is supplying all the necessities of all the living entities. That is God. God is not beggar. God fulfills everyone's necessities, practically. That is... People are unhappy by so-called economic development. Everyone is competing. They have no satisfaction. Without God, godless civilization has created unnecessary competition. But if people become God conscious, he'll be satisfied. Yenātmā suprasīdati. The very basic principle of devotional service will make one happy."
