Srimad-Bhagavatam Lectures

If you are actually serious about entering into the kingdom of God, Vaikuṇṭha, then you should be very much careful about these four principles of restriction.

Lecture on SB 6.1.34-39 -- Surat, December 19, 1970:

So our Kṛṣṇa consciousness movement, following the footsteps of Lord Caitanya, we are also following the same principles under the authority of Lord Caitanya. When we accept somebody in our society as initiated member we put forward this obligation, restriction, that "No more illicit sex life, no more gambling, no more intoxication and no more animal food." That is necessary. If you accept spiritual life, at the same time go on committing sinful activities, then you will never be able to progress. That is not possible. Because in the Bhagavad-gītā it is clearly said by Kṛṣṇa, yeṣām anta-gataṁ pāpaṁ janānāṁ puṇya-karmāṇām: "Persons who are completely freed from all contamination of sinful activities and simply engaged in pious activity, they only are admitted in devotional service." So if you are actually serious about entering into the kingdom of God, Vaikuṇṭha, then you should be very much careful about these four principles of restriction. No illicit... You cannot have any sex life without being married. That is sinful activity. You cannot indulge in intoxication. You cannot eat anything which is beyond the jurisdiction of your food. For you, for a human being, the food is, I mean to say, given there, quota, that "You can eat grains. You can eat fruits. You can eat flowers, vegetables. You can eat milk." That is sattvikāhāra, foodstuff prepared from vegetables, fruits, grains, sugar, and milk products. That's all. That is sattvika. That is allotted for the human being. You cannot imitate the cats and dogs: "Because they are eating meat, I also meat... Meat also is my food." They put forward, "Everything is food." So why don't you eat stool? That is also food—for the hog. So we must have discrimination, that what sort of food we shall take. Not that like hogs, anything will be accepted. That is humanity. So in this way, actually if we enter, if we want to enter into spiritual life, then these four principles of restriction must be observed.
