Now you have got sense, you are human being—tapo divyam (SB 5.5.1). Now you engage yourself in that tapasya. Yajña-dāna-tapaḥ-kriya na tyājyaṁ kāryam eva tat. Yajña, dāna and tapasya. Kṛṣṇa says: "These things are not to be given up." That is human civilization. Yajña-dāna-tapaḥ-kriya na tyājyaṁ kāryam eva tat: "It must be done." So if we do not do that, then you are not human being. We are not . . . we are losing the chance of becoming purified, and again implicated in the cycle of birth and death.
So these things can be very easily done, as it is said here, tad api īśa āṅghri-sevayā, simply by dedicating yourself at the lotus feet of Īśa, the supreme controller. Īśa means controller. Jagadīśa. God's another name is Jagadīśa. He is the controller of the whole universe. So īśāṅghri-sevayā. That is the only way. So that seva begins from tongue. Sevonmukhe hi jihvādau (Brs. 1.2.234). You can begin īśa-seva by the tongue, service. Chanting Hare Kṛṣṇa, that is also by tongue, and eating prasādam. Very easy. Caitanya Mahāprabhu has given us this easy program. So don't deviate from this. Chant Hare Kṛṣṇa and take prasādam. Make life simplified and be happy. That is Kṛṣṇa consciousness movement.
