So Lord Caitanya, taking compassion on these poor fellows, He taught love of Godhead. If you love Kṛṣṇa, then you will feel pleasure. Ānandamayo 'bhyāsāt (Vedānta-sūtra 1.1.12). In the Vedānta-sūtra it is said that "Every living creature is searching after pleasure." Pleasure. Therefore we have presented this small booklet, that Kṛṣṇa is the Reservoir of Pleasure.
If you can love Kṛṣṇa, then you will get pleasure. Otherwise, there is no pleasure. You will be frustrated. This is a fact. If you take it, it is nice. If you don't take it, then that is your misfortune.
So Lord Caitanya taught this love of Kṛṣṇa. Therefore one of His first disciples, Rūpa Gosvāmī, when he first met Lord Caitanya at Prayag, Allahabad, he offered his respects by composing one verse in Sanskrit:
namo mahā-vadānyāya
kṛṣṇa-prema-pradāya te
kṛṣṇāya kṛṣṇa-caitanya-
nāmne gaura-tviṣe namaḥ
(CC Madhya 19.53)
He said: "My dear Lord Caitanya, You are the most magnanimous personality in this world, most munificent, charitable. You are giving the most nice thing. What is that? Kṛṣṇa-prema, love of Kṛṣṇa." There are many charitable institution and foundation, they are giving charities to many institution and many function. But here Lord Caitanya's charity, giving free the love of Kṛṣṇa, that was very much appreciated by Rūpa Gosvāmī, and therefore he said, namo mahā-vadānyāya kṛṣṇa-prema-pradāya te, kṛṣṇāya kṛṣṇa-caitanya-nāmne. And this love of Kṛṣṇa cannot be bestowed by anyone else except Kṛṣṇa Himself.

So all the great sages . . . even the father of Śukadeva Gosvāmī, Vyāsadeva, who is the compiler of so many Vedic literature, he also came there to hear his sixteen-years-old boy. He was so elevated. It does not matter whether a man is old or young, it is the question of knowledge. So Śukadeva Gosvāmī was so elevated that so many persons assembled there. And the Sūta Gosvāmī, who spoke the Śrīmad-Bhāgavatam for the second time amongst the sages of Naimiṣāraṇya, he was also present in that meeting, and he heard from Śukadeva Gosvāmī, and he repeated to the sages of Naimiṣāraṇya.
So, śrī-kṛṣṇa-śravaṇādhi-prāyeṇa parama-praśna kṛta eṣa tu varīyan (SB 2.1.1). Śukadeva Gosvāmī is congratulating Mahārāja Parīkṣit that, "You have raised the question of Kṛṣṇa, understanding Kṛṣṇa. It is very welcome." Yaḥ praśno 'pi śrotavyAdiṣu paraṁ: "Such kind of question is the topmost question. Topmost question. There is no more better question than this." In other words, when you become inquisitive to understand the Kṛṣṇa consciousness, then that very questions will elevate you to the highest perfectional stage.
