Immortality is our birthright as Krishna's eternal parts; achieve it through tapasya and sense control, not material science.Listen — Srila Prabhupada Uvaca
Śrī Caitanya-caritāmṛta, Ādi-līlā 1.11 — April 4, 1975, Māyāpur 750404CC-MAYAPUR [32:54 Minutes] CcAdi-01.011_750404CC-MAYAPUR Nitāi: Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [Prabhupāda and devotees repeat] [leads chanting of verse, etc.] yasyāṁśāṁśāṁśaḥ parātmākhilānāṁ poṣṭā viṣṇur bhāti dugdhābdhi-śāyī kṣauṇī-bhartā yat-kalā so 'py anantas taṁ śrī-nityānanda-rāmaṁ prapadye [Cc. Ādi 1.11] [break] [00:55] "I offer my respectful obeisances unto the feet of Śrī Nityānanda Rāma, whose secondary part is the Viṣṇu lying in the ocean of milk.
That Kṣīrodakaśāyī Viṣṇu is the Supersoul of all living entities and the maintainer of all the universes. Śeṣa Nāga is His further subpart." Prabhupāda: yasyāṁśāṁśāṁśaḥ parātmākhilānāṁ poṣṭā viṣṇur bhāti dugdhābdhi-śāyī kṣauṇī-bhartā yat-kalā so 'py anantas taṁ śrī-nityānanda-rāmaṁ prapadye [Cc. Ādi 1.11] So all these Viṣṇu description beginning from Kāraṇodakaśāyī, Mahā-Viṣṇu, who is producing universes... Then next Viṣṇu is Garbhodakaśāyī, means the same Mahā-Viṣṇu entering in each and every universe. Then again, the same Viṣṇu, for maintenance of this material world, is lying on the kṣīrabdhi, ocean of milk. And the same Viṣṇu, Kṣīrabdhiśāyī Viṣṇu, is maintaining not only these universal affair, but also He is entering in each and every living being's heart, even within the atom.
This is the expansion of viṣṇu-tattva, viṣṇu-tattva within this material world. So just imagine. For creating and maintaining, sustaining, the whole material world is a network of Viṣṇu's activities, and some rascal says, "There was chunk, and there was creation." This creation is so easy? And maintain them, whole the creation?
If you create some center of our Kṛṣṇa consciousness movement, how much strain you have to exert to maintain the standard, status quo. Similarly, there are so many universes created, maintained. And there is another phase, annihilation. That is the process of material creation. We have got experience.
Anything material is created is... The beginning, there is a date, and it is maintained for sometimes, then it is annihilated. Anything you take—this body, your body, my body—it is created a certain date, and it is maintained for a certain number of years, and again it is annihilated. This is material world.
Bhūtvā bhūtvā pralīyate [Bg. 8.19]: "It manifests sometimes and again disappears." This is called material world, and because it is never eternally sustained, therefore it is called māyā. It is not false, as the Māyāvādī philosophers says, "It is false." It is not false. Lord Viṣṇu is taking so much care to create this material world. How you can say it is false?
It is not false? It is fact, but it is temporary. This is the difference between the material world and the spiritual world. In the spiritual world there is no creation and no destruction.
