Bhagavad-gita As It Is Lectures

So one is trained up as a brahmacārī, and he is sufficiently given knowledge, that "Don't be entangled with these material affairs. Don't be entangled. Try to avoid. But if you are still unable, your sex impulse is very strong, all right, then you go and marry."

Lecture on BG 1.32-35 -- London, July 25, 1973:

So anyway, the family attraction is required for regulated life. If there is no family attraction, there is no regulated life. We have got very good experience of these things. So family attraction required. It is not that it is rejected. It is required for regulated life. Unregulated life cannot make any progress. Therefore, in the Vedic civilization, the gṛhastha-āśrama is recommended. Everyone should be married and everyone should live. If possible let him live—a brahmacārī. First of all the brahmacārī-āśrama is given there, austerity, under the guidance of the spiritual master. So the idea is not to be entangled. Brahmacārī has no connection with worldly affairs. He's simply interested with the order of the spiritual master. That is called brahmacārī. So one is trained up as a brahmacārī, and he is sufficiently given knowledge, that "Don't be entangled with these material affairs. Don't be entangled. Try to avoid. But if you are still unable, your sex impulse is very strong, all right, then you go and marry." This is the process. First of all he is taught to be vairāgī. Vairāgya. This whole Kṛṣṇa consciousness movement may be called vairāgya-vidyā.
