Just like in your country it is very chilly in the morning to take bath, a little difficult task. But does it mean that those who are devotees, they will stop taking bath? No. Even it is chilly, cold, one must take bath. The duty must be done. The duty must be done, even it is little suffering. That is called tapasya. Tapasya means we must prolong or proceed with . . . with our Kṛṣṇa consciousness business in spite of all dangerous and calamitous condition of this world. This is called tapasya. Tapasya means voluntarily accepting the difficulties of life. Sometimes tapasya, in the system of tapasya, in hot season, summer, in scorching heat of the sun, still they ignite some fire all round and sit down in the midst and meditate. There are some processes of tapasya like that. In chilly cold one goes into the water up to the neck and meditates. These things are prescribed in tapasya.
But Lord Caitanya Mahāprabhu does not give you such prescription. He gives you very nice program: chant, dance and take prasādam. (laughter) Still we are unwilling. We cannot accept this tapasya. You see? We are so fallen. Su-sukhaṁ kartum avyayam (BG 9.2). This is a kind of tapasya which is very easy to do, and it is very pleasant. Still, we are not agreeable. We shall rot in the street, lie down anywhere and everywhere, and still I shall drink and have sex and lie down. So what can be done? We are giving good facilities: "Come here, chant, dance and live very peacefully and take kṛṣṇa-prasādam. Be happy." But people will not accept. That is called misfortune.
Caitanya Mahāprabhu therefore said: etādṛśī tava kṛpā bhagavan mamāpi durdaivam īdṛśam ihājani nānurāgaḥ (CC Antya 20.16, Śikṣāṣṭaka 2). Caitanya Mahāprabhu says, nāmnām akāri bahudhā nija-sarva-śaktiḥ: "In the transcendental holy name of God, Kṛṣṇa, there is all potencies." As Kṛṣṇa has got unlimited potencies, similarly in the name, holy name of Kṛṣṇa, there is unlimited potency.
