So here is also another statement from Śrīmad-Bhāgavatam. This was spoken by Brahmā to his disciple Nārada. Nārada questioned him that "So far we know, that you are the supreme, but you also sometimes meditate and worship somebody." So in that connection Brahmā explained that "We are not supreme. We are all appointed agents. Supreme is the Supreme Personality of Godhead." Viśvaṁ puruṣa-rūpeṇa paripāti triśakti-dhṛk. Viśvam, this cosmic manifestation, is being maintained by His threefold energies. Triśakti-dhṛk. Triśakti means three kinds of energies. When it is materially conceived, the three kinds of energies are the modes of goodness, the modes of passion and the modes of ignorance. And when they are spiritually conceived, the same three kinds of energies are manifested as spiritual potency, material potency and marginal potency. So anyway, the Lord is always full with different kinds of energies, of which these three are main divisions.
manvantarāvatāra ebe śuna, sanātana
asaṅkhya gaṇana tāṅra, śunaha kāraṇa
Now Lord Caitanya has explained about... Out of six kinds of incarnations, He has explained to you the incarnation of puruṣāvatāra, three, then līlāvatāra, then guṇāvatāra. Three kinds of incarnations are already explained. Now the remainder, three kinds of incarnations, manvantarāvatāra, yugāvatāra, and śaktyāveśāvatāra, He is going... Out of that three, first the manvantarāvatāra, Manu... So Lord Caitanya says that "I shall now explain to you about the manvantavatāra." And He says, manvantarāvatāra ebe śuna, sanātana: "My dear Sanātana, just now I shall explain to you about the manvantarāvatāra. You hear it." Asaṅkhya gaṇana tāṅra, śunaha kāraṇa: "And this manvantarāvatāra... So far other incarnations are concerned, we have somehow counted three or say ten, like that. But here, when we speak of manvantarāvatāra, they are countless." Asaṅkhya. Asaṅkhya means countless. Nobody can count how many manvantarāvatāras are there. How it is so? He is explaining. Brahmāra eka-dine haya caudda manvantara: "In one day of Brahmā, in one day of Brahmā..." That you have calculated according to Bhagavad-gītā: sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ (BG 8.17). Brahmaṇo, or Brahmā, arhat. Arhat means one day, twelve hours. What is that twelve hours according to our calculation? Sahasra-yuga-paryantam, sahasra, one thousand yugas. And what is the duration of yuga? Four million, three hundred thousands of years, one yuga. Such one thousand, that makes Brahmā's one day, twelve hours. Similarly night, twelve hours. Similarly one month. In this way he has got hundred years' duration of life.
