Prabhupāda: Ā-brahma-bhuvanāl lokāḥ... Within this material world, these persons who are doing pious activities, they are promoted to the higher planetary systems. But even if you go to the Brahmaloka—that is the highest—where you can get millions of years, your life duration, but still, kṣīṇe puṇye martya-lokaṁ viṣanti (BG 9.21), you have to come back.
Chandobhai: Sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17), rātriṁ...
Prabhupāda: Now He explaining what is Brahmaloka. That one day of Brahmā, you cannot calculate. And still, you have to die.
Dr. Patel: Twelve hundred yugas is called one Brahmā.
Chandobhai: So our hundred years is nothing for...
Prabhupāda: It is nothing.
Chandobhai: It is a moment only.
Dr. Patel: Twelve hundred yugas.
Prabhupāda: No, no, no. Not twelve hundred yugas. One thousand yugas. One thousand. Sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17).
Dr. Patel: Sahasra-yuga means four yugas, (Hindi) like that...
Prabhupāda: That... Four yugas multiplied by one thousand.
Dr. Patel: By one thousand.
Prabhupāda: Yes.
Dr. Patel: Four thousand.
Prabhupāda: So four yuga means forty-three lakhs of years. Now, add three zeroes. Forty-three lakhs of years, add three zeroes. Then how many?
Dr. Patel: About four, about... Car...
Prabhupāda: Eh? Forty-three lakhs, as...
Dr. Patel: Car ardha...
Prabhupāda: Forty-three, eight zeroes.
Dr. Patel: Car... (Gujarati)
Prabhupāda: This is Brahmā's twelve days, uh, twelve hours.
Dr. Patel: Rātri, (Gujarati)
Chandobhai: Why not... There's a little question to ask: What are the Pitṛloka, Martyaloka and this...?
Prabhupāda: They are planets.
Chandobhai: And the Brahmaloka and all the...?
Prabhupāda: Yes. They are different... Just like Candraloka, Sūryaloka, Vāyuloka.
Chandobhai: What is that Pitṛloka actually?
Prabhupāda: Pitṛloka means the... There is a, called a Pitṛloka.
Chandobhai: But then in the Pitrloka is it may be that, there may be remembrances of the charity, activities, and all these things or...
Prabhupāda: No, these are all material.
Dr. Patel: Pitṛloka (Gujarati) They are all your past pitṛs.
Chandobhai: No, let us hear from him.
Prabhupāda: Pitṟn yānti... Devān yānti... What is that? Deva... Pitṟn yānti pitṛ-vrataḥ. So those who are just like fond of performing śraddhās, karma-kāṇḍa, they go to the Pitṛloka.
Dr. Patel: These are all, I mean, ordained to perform śraddhā, all Vaiṣṇavas.
Prabhupāda: Yes. No, Vaiṣṇavas do not do so.
Dr. Patel: We are... We, all are, all of us, are we not doing...
Prabhupāda: No.
Dr. Patel: Śraddhā ceremony...
Prabhupāda: The Vaiṣṇava, Vaiṣṇava has no duty except serving Kṛṣṇa. That's all.
Dr. Patel: That's right. But a Vaiṣṇava family...
Prabhupāda: No.
Chandobhai: Gṛhasthas, gṛhasthas.
Dr. Patel: Gṛhasthas.
Prabhupāda: He, whatever he may be. That is stated, that is stated that...
Dr. Patel: Only Jains can do.
Prabhupāda: That is stated that pitṛṇām. No, what is that verse? Devarṣi-bhūtāpta-nṛnam-pitṛṇām (SB 11.5.41). We are... Just like we are indebted to our forefathers, family, similarly we are indebted to devas, the demigods. Just like the sun is supplying light. So we are indebted. Deva, ṛṣi, to the great, big, big, saintly ṛṣis. They have given us the śāstras. Devarṣi, devarṣi bhūtā... Bhūtā, ordinary living entities. Just like you are taking milk from the cows. And another, horse, is giving me service. So devarṣi-bhūtā apta, relatives. We take so much help from relatives. Devarṣi-bhūtāpta-nṛnam, ordinary human beings. Pitṛṇām. And the pitṛs. So we are debted to so many. If you want to clear up the debts, it will take millions of births. (laughter) So devarṣi-bhūtāpta-nṛnam-pitṛṇāṁ nayaṁ kiṅkara na ṛni ca rājan (SB 11.5.41). This man is neither servant nor indebted. Who? Sarvātmanā yaḥ śaraṇaṁ mukundam. One who has taken... That Kṛṣṇa says, that "You just surrender unto Me. I will protect you." So if he does not do anything else... One may think that he is being entangled in sinful activities because he does not do other duties. But Kṛṣṇa says, ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi (BG 18.66). So one who has taken shelter, full shelter unto Kṛṣṇa, he doesn't require to do any so-called social, political and other duties. He doesn't require.
