Pradyumna: "Generally people have many wrong conceptions about both of them. The wrong conception of the jīvātmā is to identify the material body with the pure soul. And the wrong conception of Paramātmā is to think Him on an equal level with the living entity. But both misconceptions can be removed by one stroke of bhakti-yoga, just as in the sunlight both the sun and the world and everything within the sunlight are properly seen."
"In the darkness no one can see the sun, nor himself, nor the world. But in the sunlight one can see the sun, himself and the world around him. Śrīla Śukadeva Gosvāmī therefore says that for purification of both wrong conceptions, the Lord presented His eternal form before Brahmājī, being fully satisfied by Brahmā's nondeceptive vow of discharging bhakti-yoga."
Prabhupāda: Bhaktyā mām abhijānāti (BG 18.55). That is clearly said in the Bhagavad-gītā. Kṛṣṇa says, "If you want to know Me, then you have to accept this bhakti-yoga. No other means will . . ." because without full surrender unto Kṛṣṇa, nobody can know Him. Even a very important man in this world, you cannot know him by challenge. But if you surrender, it is possible to know him. Then? (break)
Bhakti-yoga therefore requires little tapasya, not playthings. Tapasya, that, "We are addicted to so many sinful activities. We must give it up." That is tapasya. "We must observe fasting on Ekādaśī day, on Lord's birthday." These are tapasya. If we do not . . . "We must chant sixteen rounds. We must observe the rules and regulation." This is tapasya. Don't make God very cheap thing: "Oh, it is very cheap thing." No. It has been made very easy for the Kali-yuga people because they cannot undergo any kind of tapasya. There is simple tapasya—"Chant sixteen rounds. Don't take this. Don't do this, four items. Take prasādam. Don't take anything . . ." So nothing is stopped. A little regulated, that this much, if we do not do, then how we can expect to see God and understand God? Tapo divyam (SB 5.5.1).
If simply we remain like hogs and cats and dogs, then how it is possible to realize God? Paraṁ pavitram. If I do not become pavitra myself, pure, how I can see the supreme pure? It is impossible. Tapasya must be there. But for this age the tapasya has been minimized. Brahmā is the most important person within this universe. He underwent tapasya for a hundred years. Then he could see God and realize God. You cannot go such tapasya, undergo such tapasya. That is not possible in this age.
He has simply asked, Caitanya Mahāprabhu, very kindly. He is God. He is giving His own prescription: harer nāma harer nāma harer nāmaiva kevalam, kalau nāsty eva nāsty eva nāsty eva (CC Adi 17.21): "Simply you chant." Because in this age it is very difficult . . . every process . . . the yoga system, that is also tapasya. The jñāna system, that is also tapasya. Karma system also, that is also great tapasya. Karma means not working hard in the factory like cats and dogs. No, that is not karma. Karma means to perform the ritualistic ceremonies, big, big yajñas, sacrifices. That is karma. So where is your money? You cannot provide your food even for two meals.
