Prabhupāda: If you become devotee, you can give up this nonsense practice, illicit sex, meat-eating. Why meat-eating? We have got so many nice preparation Sundays—rasagullā, halavā, purī, luci. Why shall I eat this nasty thing, rotten? It is slaughtered and kept for 3,000 years in the refrigerator (laughter), and this rotten thing is taken and eaten. So why should we take that? Why smoking, this nonsense? It is stated in every cigarette box it is injurious to health or something like . . . what is that? Devotee: Warning.
Prabhupāda: Warning. But still they're eating that poison; they're drinking. So these are anarthas, unwanted things. By bad association we are habituated to this nonsense practice. But if you become a devotee and render service to Kṛṣṇa under the direction of your spiritual master, these things will automatically vanquish. Anartha-nivṛttiḥ syāt tato niṣṭhā (CC Madhya 23.14-15), then your faith becomes firm. Tato niṣṭhā tato ruci athāsaktis. Asakti: it is spontaneous attraction.
So religious principle means you have to execute the preliminary formulas, but the ultimate end will be you'll have spontaneous attraction for hearing about God, or Kṛṣṇa. That is wanted. If that thing is not done, then you are simply wasting time by going to church or temple or mosque or any nonsense. Notpādayed yadi ratiṁ śrama eva hi kevalam (SB 1.2.8). Simply waste of time.
So don't become a show bottle of religious man. Actually try to understand what is religion, what is God, and make your life successful.
