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.
