The brahmacārī is educated in that way. Up to twenty-five years he cannot see a young woman. He cannot see even. This is brahmacārī. He cannot see. Then he is trained up in that way, that he may continue a brahmacārī life. Naiṣṭhika-brahmacārī. But if he's unable, then he's allowed to marry. That is called gṛhastha life, householder life. Because between twenty-five years to fifty years, this is the youthful time, so his lusty desires are very strong. One who is not able to control. . . Not for all. There are many naiṣṭhika-brahmacārī. Naiṣṭhika-brahmacārī—throughout the life, celibacy. But that is not possible in this age, neither it is possible to become a brahmacārī. The time is changed, this age. Therefore you can control your lusty desire by Kṛṣṇa consciousness. Otherwise it is not possible.
Yad-avadhi mama cetaḥ kṛṣṇa-padāravinde. One emperor, he was king, so naturally he was lusty also. So he gave up this life, became a devotee. So when he was perfectly situated, so he said, Yāmunācārya—he was the guru of Rāmānujācārya—so he said that yad-avadhi mama cetaḥ kṛṣṇa-padāravinde: "Since I've trained my mind to be engaged in the service of the lotus feet of Kṛṣṇa," yad-avadhi mama cetaḥ kṛṣṇa-padāravinde nava-nava-dhāmany udyataṁ rasa, "daily I am offering service to Kṛṣṇa, I am getting new, new pleasure." The spiritual life means. . . If one is actually situated in spiritual life he'll get spiritual pleasure, transcendental bliss, by serving more and more, new and new. That is spiritual life. So Yāmunācārya said, yad-avadhi mama cetaḥ kṛṣṇa-padāravinde nava-nava-dhāmany udyataṁ rantum āsīt: "When I am now realizing transcendental pleasure every moment by serving Kṛṣṇa's lotus feet," tad-avadhi, "since then," bata nārī-saṅgame. . . Sometimes we enjoy subtle pleasure, thinking of sex life. That is called nārī-saṅgame. Nārī means woman, and saṅga means union. So those who are practiced, so when there is actually no union, they think of union. So Yāmunācārya says that "Not actually union with woman, but if I think of union," tad-avadhi bata nārī-saṅgame smaryamāne, smaryamāne, "simply by thinking," bhavati mukha-vikāraḥ, "oḥ, immediately I becomes disgusted: 'Aḥ, what is this nasty thing?' " Suṣṭhu niṣṭhī. . . (makes spitting sound) This is perfect. (chuckles) This is perfection. Yes. So long we'll think of, that is called subtle sex, thinking. They read the sex literature. That is subtle sex. Gross sex and subtle sex. So one has to become completely free from these lusty desires, not to become implicated which will never be satisfied—unsatiated, duṣpūram.
