Viṣaya means sense enjoyment. Sense enjoyment. So one has to give up this practice of sense enjoyment. Then he becomes purified. There is no prohibition for eating, but there is prohibition of eating things are rejected, which are rejected, amedhya. Eating is not stopped, but you cannot eat anything which does not . . . which is not accepted by Kṛṣṇa. That is called anācāra. If you eat something which is not accepted by Kṛṣṇa . . . because our life, Kṛṣṇa consciousness life, means to be always eternal servant of Kṛṣṇa. As the servant eats the remnants of foodstuff left by the master, similarly, we are servants of Kṛṣṇa, we also eat, but we eat remnants of foodstuff which is left by Kṛṣṇa. That is called prasādam, mahā-prasādam.
So we have to, I mean to say, mend our life in such a way that kṛṣṇera saṁsāra kara, chāḍi anācāra. We have to give up anācāra, forbidden things, sinful things. Striyaḥ sūnā pānaṁ dyūtaṁ yatra pāpaś catur-vidhaḥ (SB 1.17.38). There are four kinds of sinful activities. Basic principle of sinful life is avaidha, illicit sex life. Avaidha stri-saṅga. Striyaḥ sūnā, unnecessary animal killing; pāna, drinking, intoxicant; and gambling. We have to give up these four principles. Then our life becomes pure. If we give up these four principles and chant Hare Kṛṣṇa mantra, then we become perfect. How it is? You can see the examples. These European, Americans, they were accustomed to all these practices. That is their daily affair. But they have given up this. Now you see how they are saintly.
So the thing is not very difficult, but one has to accept the principles. Then one lifes becomes perfect. They do not know what is perfection of life. People are thinking that material advancement is perfection of life. No. That is not perfection of life. Because even if you make nice material arrangement, you cannot enjoy it. At any time you shall be kicked out. Where is your perfection? Suppose you have very nice apartment, very nice, good bank balance, very nice wife, children, everything is all right. But is there any guarantee that you can enjoy them? Is there any guarantee? At any moment you shall be out. This is not perfection. First of all make guarantee that, "Whatever I am preparing for, very happy life in this material . . . they will be permanent. I will not be kicked out." Then it is perfection. But there is no such guarantee.
Therefore this is not perfection of life. Perfection of life is that when there is guarantee of no more birth, no more death, no more old age and no more disease. That is perfection. That can be achieved by Kṛṣṇa consciousness, not by material way. Hariṁ vinā na mṛtiṁ taranti. If you want to be eternal, blissful, eternally blissful and full of knowledge, sac-cid-ānanda-vigraha (Bs. 5.1), then we have to take to Kṛṣṇa consciousness. There is no other way. There is only way. Mām upetya kaunteya duḥkhālayam aśāśvatam (BG 8.15). If you are serious about perfection of life, then one has to take to this Kṛṣṇa consciousness. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65), mām evaiṣyasi asaṁśayam: "Without any doubt, you shall come to Me."
