Pradyumna: "In the Bhagavad-gītā (BG 7.3) it is said that out of many thousands of ordinary men, one fortunate man endeavors for perfection of life. Mostly they are conducted by the modes of passion and ignorance, and thus they are engaged always in lust, desire, hankerings, ignorance and sleep. Out of many such manlike animals, there is actually a man..."
Prabhupāda: Manlike animals. They show with two hands, two legs, but actually they are animals. Four-legged. Two legs have been transformed into two hands. Go on.
Pradyumna: "Out of many such manlike animals, there is actually a man who knows the responsibility of human life and thus tries to make life perfect by following the prescribed duties. And out of such many thousands of persons who have thus attained success in human life, one may know scientifically about the Personality of Godhead, Śrī Kṛṣṇa."
Prabhupāda: Yes. So it is not so easy to understand Śrī Kṛṣṇa. Manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye, yatatām api siddhānām: (BG 7.3) "Those who have endeavored for perfection of life, out of many such persons, one can hardly understand Kṛṣṇa." It is not so easy. But it is by Kṛṣṇa's grace. Kṛṣṇa being very compassionate with these fallen souls of this age, He appeared as Lord Caitanya and distributed Kṛṣṇa. That is His prerogative. That is His right. If Kṛṣṇa wants to distribute Himself freely, that is a different thing. Otherwise, it is not so easy to understand Kṛṣṇa. Just like to earn one million dollar is not so easy. But if you are fortunate, you meet somebody who can distribute million dollars at a time, that is a different thing. Therefore Lord Caitanya Mahāprabhu was recognized by Rūpa Gosvāmī, namo mahā-vadānyāya kṛṣṇa-prema-pradāya te: (CC Madhya 19.53) "My dear Lord, You are the most munificent of all incarnations. The other incarnations, people could not understand, but You are freely distributing Yourself." Kṛṣṇa-caitanya-nāmne. Kṛṣṇāya kṛṣṇa-caitanya-nāmne gaura-tviṣe namaḥ. Therefore we have to follow the footsteps of Rūpa Gosvāmī, rūpānuga. Then we can understand Lord Caitanya. And if we get favor of Lord Caitanya, we can very easily understand Kṛṣṇa. This is the process. Go on.
Pradyumna: "In the same Bhagavad-gītā (18.55) it is also said that scientific knowledge of Śrī Kṛṣṇa is understood only by the process of devotional service, or bhakti-yoga..."
Prabhupāda: Yes. Here also it is confirmed: bhagavad-bhakti-yogataḥ. It is not said, "By mystic yoga, by haṭha-yoga, by jñāna-yoga, by karma-yoga." No. Bhagavad-bhakti-yogataḥ. If you want to understand the science of God, then we have to adopt this devotional service. Not by other yogas. Otherwise, in Bhāgavata it would have been said "By karma-yogataḥ, by jñāna-yogataḥ, by haṭha-yogataḥ, by dhyāna-yogataḥ." No. It is clearly said, bhagavad-bhakti-yogataḥ. Bhagavat-tattva-vijñānaṁ mukta-saṅgasya jāyate (SB 1.2.20). If you are still after jñāna-yoga, dhyāna-yoga, you cannot understand Kṛṣṇa, God. It is clearly said. In the Bhagavad-gītā also, it is clearly said, bhaktyā mām abhijānāti (BG 18.55). Simply through devotional service.
So if you want to know God, then you have to follow the prescribed rules and regulations of bhagavad-bhakti-yoga. It is very simple. It is made very easy, especially in this age: simply by chanting Hare Kṛṣṇa mantra. It's so made easy, but we are so unfortunate that we do not take advantage of this. Etādṛśī tava kṛpā bhagavan mamāpi durdaivam īdṛśam ihājani nānurāgaḥ. Lord Caitanya Mahāprabhu laments, "My dear Lord, You are so compassionate and merciful upon us that in this age You have descended in Your, as Your name, and one can chant this name without any regulation, without any regulation." Niyamitaḥ smaraṇe na kālaḥ. Any time, any circumstances, one can chant this Hare Kṛṣṇa mantra. Kṛṣṇa has become so liberal. But Caitanya Mahāprabhu says, etādṛśī tava kṛpā bhagavan mamāpi: "My dear Lord, although You are so much merciful upon me, still, I am so unfortunate." Etādṛśī tava kṛpā bhagavan mamāpi durdaivam īdṛśam, "I am so unfortunate," durdaivam īdṛśam ihājani na, "I could not be attached to chanting of mantra. Oh, I am so unfortunate." You see? The things have been made so easy, actually, but unfortunate class of men, they cannot take to it.
Thank you very much. Hare Kṛṣṇa.
