To speak frankly, there is no necessity even for marrying. There is no necessity. If one can remain a brahmacari all through, that is a great benefit. Great benefit. Yan-maithunadi-grhamedhi-sukham hi tuccham. What is the benefit? It is increasing botheration. But they are trying to get out of botheration. Just like we see advertisement, "One, two, three, bas — no more children." And other… "What I shall do?" "Now, kill, that's all. Kill them by contraceptive method or directly. Don't allow more than one, two, three children." They understand that "This is botheration." And the sastra also says, "Botheration."
yan-maithunadi-grhamedhi-sukham hi tuccham
kanduyanena karayor iva duhkha-duhkham
trpyanti neha krpana bahu-duhkha-bhajah
kandutivan manasijam visaheta dhirah
"All right, I have begotten one child. I have to take care of, so much care always." But, "All right, you have trouble, taken so much trouble. Stop here. No more." "No, again." Trpyanti neha krpana bahu-duhkha-bhajah. There's so many botherations, but still, we do it practically. Why? It is said that ajitatmanah, cannot control the senses, become victimized, victims of sense enjoyment, ajitatmanah.
