Śrīmad-Bhāgavatam
[Canto 4, Ch. 26]
no animal killing, no intoxication, no illicit sex, and no gambling. This Kṛṣṇa consciousness movement is the only means by which the sinful activities of men in this Kali-yuga can be counteracted.
TEXT 6
तीर्थेषु प्रतिद्दृष्टेषु राजा मेघ्यान् पशून् वने । यावदर्थमलं लुब्धो हन्यादिति नियम्यते ॥ ६ ॥
tīrtheṣu pratidṛṣṭeṣu rājā medhyān paśūn vane yāvad-artham alam lubdho hanyād iti niyamyate
tīrtheṣu —in holy places;  pratidṛṣṭeṣu —according to the direction of the  Vedas ;  rājā —a king;  medhyān —fit for sacrifice;  paśūn —animals;  vane —in the forest;  yāvat —so much as;  artham —required;  alam —not more than that;  lubdhaḥ —being greedy;  hanyāt —one may kill;  iti —thus;  niyamyate —it is regulated.
TRANSLATION
If a king is too attracted to eating flesh, he may, according to the directions of the revealed scriptures on sacrificial performances, go to the forest and kill some animals that are recommended for killing. One is not allowed to kill animals unnecessarily or without restrictions. The  Vedas  regulate animal killing to stop the extravagance of foolish men influenced by the modes of passion and ignorance.
PURPORT
The question may be raised why a living being should be restricted in sense gratification. If a king, to learn how to kill, may go to the forest and kill animals, why should a living entity, who has been given senses, not be allowed unrestricted sense gratification? At the present moment this argument is put forward even by so-called  svāmīs  and  yogīs  who publicly say that because we have senses we must satisfy them by sense gratification. These foolish  svāmīs  and  yogīs , however, do not know the injunctions of the  śāstras . Indeed, sometimes these rascals come out to defy the  śāstras . They even publicly announce that there should be no more  śāstras , no more books. “Just come to me,” they say, “and I shall touch you, and you will become immediately spiritually advanced.”
