Srimad-Bhagavatam Lectures

Everyone may remain in his own position. It doesn't require to change. Just like one gentleman was asking whether, for spiritual advancement, one has to live in the temple. I said, "No. There is no such hard and fast rule that one should live in the temple." You can live anywhere, but the spiritual practices should be going on. Kṛṣṇa never says that you live in the temple or you go to the jungle or Himalaya. Never say.

Lecture on SB 2.2.5 -- New York, March 5, 1975:

In Hawaii there are so many jungles, enough fruit—mango, papaya, and many others, banana, then pineapple, guava, so many fruits. So going to the jungle means to be free from food problem, enough food. And then water. . . Water is river. Therefore it is said, sarito 'py aśuṣyan, "Do you think that all the rivers are dried up?" Enough water. Then you may say that "I must require some pot to take the water." No. You take water like this. (shows hands together) You drink. "Then where shall I live?" Ruddhā guhāḥ kim: "Do you think all the caves of the mountains they are now closed?" There are many caves. If you want at all shelter, they already there are natural rooms, apartment. (laughter) You can live there. Ruddhā guhāḥ kim. "And above all," Śukadeva Gosvāmī says, kim ajito 'vati nopasannān. Na avati upasannān. Upasannān means those who have surrendered.

Ajita. . . God's another name is Ajita. A means "not," and jita means "conquered." Nobody can conquer God. That is God. God is never conquered by anyone. He conquers everyone. God is conquered by His devotee only, not by the demons. The demons are conquered by God. But devotee can conquer. Ajito 'pi, jito 'pi. Although God is ajita, He becomes jita, means conquered, by His devotee. That is also stated: sthāne sthitāḥ śruti-gatāṁ tanu-vāṅ-manobhiḥ, prāyena ajita jito 'py asi tais tri-lokyām (SB 10.14.3). This process we have introduced, opening centers, that is the system in spiritual, to hear. Sthāne sthitāḥ śruti-gatāṁ tanu-vāṅ-manobhiḥ. Śruti. Śruti means this ear, aural reception. Everyone may remain in his own position. It doesn't require to change. Just like one gentleman was asking whether, for spiritual advancement, one has to live in the temple. I said, "No. There is no such hard-and-fast rule that one should live in the temple." He can live anywhere. But the spiritual practices should be going on. Kṛṣṇa never says that you live in the temple or you go to the jungle or Himalaya. Never says. You'll never find in the Bhagavad-gītā that Kṛṣṇa says Arjuna that "You give up this fighting and go to the jungle or to the Himalaya and become perfect person." No. Kṛṣṇa says, man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). You follow this principle: "Always think of Me," man-manāḥ, mad-bhaktaḥ, "you become My devotee." Man-manā bhava mad. . . mad-yājī, "Worship Me and offer your obeisances unto Me." These four things. You can do anywhere. It doesn't matter. But you do all these things. Narottama dāsa Ṭhākura says, gṛhe vā vanete thāko hā gaurāṅga bole ḍāko. Either you remain as a gṛhastha with family, wife, children—it doesn't matter—or either you live in the forest like sannyāsī, renounced. In whichever position you prefer, you can remain. But do these things: man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65).
