Prabhupada's lecture - Śrīmad-Bhāgavatam 1.15.32 - Los Angeles, December 10, 1973
So now our consciousness is immortal consciousness or mortal consciousness, that is to be seen. I am absorbed in thought of this mortal consciousness, "This is my country, this is my body, this is my family, this is my community, this is my nation..." They are all mortal. But immortal consciousness is that "I am Kṛṣṇa's." That is immortal consciousness. "Kṛṣṇa is mine, and I am Kṛṣṇa's." This is immortal consciousness. When you come to this consciousness—that is called Kṛṣṇa consciousness—then you are saved. Immortal consciousness. So long you have got temporary consciousness, then... Just like our mind changes. I accept something now; I reject something again. So this body is being manufactured according to the acceptance and rejection of my mind. The body is formed. Otherwise why we have different body? We are sitting here, so many boys and girls, ladies and gentlemen. Nobody's body will exactly tally with others' body. No. Because the face is the index of mind. You have got different types of mind; therefore you have got different types of body, not every one.
So this is to be understood. Therefore Yudhiṣṭhira Mahārāja, svaḥ-pathāya matiṁ cakre. This is meditation actually. "What I am? Wherefrom I have come? I am eternal. Why my body is not eternal? I would have been very happy if my body would have been eternal, but that is not being possible." Everyone knows. "But I desire that I may not die, my body may not be vanquished. That is my desire." But nobody is meditating upon this subject matter. They have learned some meditation—I do not know what kind of medi... This is meditation, matiṁ cakre. Svaḥ-pathāya matiṁ cakre nibhṛtātmā yudhiṣṭhiraḥ. So these things are to be solved. So Yudhiṣṭhira Mahārāja, now he will retire after this. So he will give up the kingdom. Not that... This is the Vedic system. However rich you may be, however prosperous you may be at your home or in your nation or in anyway as you think, but you have to think that "Actually these things are temporary. I am eternal. So what is my eternal function?" That is meditation. "What is my eternal function? What is my eternal duty? Where is my eternal home?" That is Kṛṣṇa consciousness.
