Room Conversation with Christians — June 20, 1974, Germany 740620R1-GERMANY [12:29 Minutes] Conv_740620R1-GERMANY Prabhupāda: Cannot find?
Devotee: Yes. In German, just... balaṁ balavatāṁ cāhaṁ kāma-rāga-vivarjitam dharmāviruddho bhūteṣu kāmo 'smi bharatarṣabha [Bg. 7.11] Prabhupāda: Hmm.
Devotee: [reads translation in German] [German discussion with guest]
Prabhupāda: Sex life, married couple, that is all right; not otherwise. That is sinful. [translated into German throughout]
Devotee: Śrīla Prabhupāda, just his objection was that in this statement in the Bhagavad-gītā doesn't clearly say no reason you should not have sex life outside of married life, they simply state religious principles, but this is...
Prabhupāda: Religious principle means married life; otherwise cats and dogs. So what is the... If everyone has without any limitation sex life, then what is the difference between cats and dogs? Religion means they are not cats and dogs, because religion is in the human society, not in the cats' and dogs' society.
Guest: I agree that in the Christian [indistinct] also. And in the life who will come, will not be sexual life in the future in the perfection state. No there will no be the sexual life Prabhupāda: Yes, in the spiritual life there is no sex life. In the spiritual world there is no sex intercourse.
