Tulsidas has said that in the ocean, the waves of the ocean, if you put one elephant, very powerful, very strong, the elephant will be washed away by the waves. But a small fish, a teeny fish, it is swimming against the waves. They take pleasure. The fish, when the waves are coming this way, the fish go in that way. Now see: you put against the waves an elephant, it will be washed away. Why elephant? Any strong thing you give. Even big, big ships, oh, it will be washed away. But a small fish, it doesn't care the waves; it goes against the waves. Why? It has taken the shelter. It has taken the shelter of the ocean. Similarly, all power belongs to Kṛṣṇa. Yatra yogeśvaraḥ hariḥ. But if anyone takes shelter of Kṛṣṇa, he becomes as powerful as Kṛṣṇa. This is the process.
So . . . but we do not know. We want to become powerful here by so-called science, so-called yoga, kuṇḍalinī and what other nonsense they are think . . . they are trying to be immortal, powerful. No, sir, that is not possible. It is not possible. Therefore, people do not know. Na te viduḥ. They do not know. Svārtha-gatiṁ hi viṣṇum. Our aim should be how to approach Viṣṇu, how to go back to home, back to Godhead. Na te viduḥ svārtha-gatiṁ hi viṣṇuṁ durāśayā. They're hoping, very durāśayā, means very badly, wrongly, that they want to be happy by adjustment of this material world. The yogic process is also another material gymnastic. We have not heard any yogī has become successful to get immortality. No. That is not possible.
Na te viduḥ svārtha-gatiṁ hi viṣṇuṁ durāśayā ye bahir-artha-māninaḥ (SB 7.5.31). Those who are trying to adjust this material world by science or yoga, without caring for Viṣṇu, what they are? Andhā. They are blind. Andhā. And their leaders? They are also blind. Andhā yathā upanīyamānāḥ andhena. One blind man is trying to lead another blind man. So what is the wrong there? Te 'pīśa-tantryāṁ baddhāḥ: they are bound up by the laws of nature, hand and legs tight. How they can become free and happy by such endeavor? That is not possible.
