Strong youth must seize the opportunity to serve Krishna eternally, escaping the cycle of birth and death through devoted practice.Listen — Srila Prabhupada Uvaca
Pradyumna: Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. Oṁ namo bhagavate vāsudevāya. [Prabhupāda and devotees respond] [leads chanting, etc.] tato yateta kuśalaḥ kṣemāya bhavam āśritaḥ śarīraṁ pauruṣaṁ yāvan na vipadyeta puṣkalam [SB 7.6.5] [02:01] Translation: "Therefore, while in material existence [bhavam āśritaḥ], a person fully competent to distinguish wrong from right must endeavor to achieve the highest goal of life as long as the body is stout and strong and is not embarrassed by dwindling." Prabhupāda: tato yateta kuśalaḥ kṣemāya bhavam āśritaḥ śarīraṁ pauruṣaṁ yāvan na vipadyeta puṣkalam [SB 7.6.5] So this should be the human activity, that śarīraṁ pauruṣaṁ yāvan na vipadyeta puṣkalam.
So long we are stout and strong and we can work very nicely, the health is quite all right, take advantage of it. It is not Kṛṣṇa consciousness movement is for the lazy fellow. No. It is meant for the strong man: strong in body, strong in mind, strong in determination—everything strong—strong in brain.
It is meant for them. Because we have to execute the highest goal of life. Unfortunately, they do not know what is the highest goal of life. The modern...
Not modern; always. Now it is very conspicuous: people do not know what is the aim of life. Anyone who is in this material world, he is in māyā, means he does not know what is the goal of life. Na te viduḥ, they do not know, svārtha-gatiṁ hi viṣṇu.
[SB 7.5.31] Svārtha-gati. Everyone is supposed to be self-interested. Self-interest is the first law of nature, they say. But they do not know what is self-interest.
He, instead of going back to home, back to Godhead—that is his real self-interest—he's going to become a dog in the next life. Is that self-interest? But they do not know it. How nature's law is working, they do not know it. Na te viduḥ.
Adānta-gobhir viśatāṁ tamisram. Matir na kṛṣṇe parataḥ svato vā. matir na kṛṣṇe parataḥ svato vā mitho 'bhipadyeta gṛha-vratānām adānta-gobhir viśatāṁ tamisraṁ punaḥ punaś carvita-carvaṇānām [SB 7.5.30] That, Kṛṣṇa consciousness, matir na kṛṣṇe. People are very much reluctant to become Kṛṣṇa conscious. Why?
