Devotee: I don't know what night pollution is.
Trivikrama: Passing semina in sleep.
Devotee: Oh.
Prabhupāda: Why it does happen? What is your explanation? Nobody can explain?
Rāmeśvara: Desire in the heart, subtle desire.
Puṣṭa Kṛṣṇa: It is nature, just...
Prabhupāda: No, no, nature... The body is made of material nature, and the eruption is coming. Why it is coming? Does it come in the dead body?
Devotee: No.
Prabhupāda: Then? What is the cause?
Paramahaṁsa: The soul, living entity.
Prabhupāda: Because the soul is there. Similarly, the Supersoul is there, and He's arranging everything. The volcano's eruption does not take automatically. When it is desired by Kṛṣṇa, then it takes place. Mayādhyakṣeṇa (BG 9.10). Why don't you read Bhagavad-gītā. "Under My superintendence." When He knows that "Now this eruption is required," immediately there is... Parāsya śaktir vividhaiva śrūyate (Cc. Madhya 13.65, purport). He has got so many potencies. One potency works. That's all. Because the living soul is there, therefore the seminal discharge takes place. Similarly, because the supreme living is there, therefore all these things are happenning. Where is the difficulty to understand? Kṛṣṇa says, viṣṭabhyāham idaṁ kṛtsnam ekāṁśena sthito jagat: (BG 10.42) "The whole worldly affair is going on because I am there." Viṣṭabhya: "I have entered into it." Don't you read in the Bhagavad-gītā? Then? And we are reading that portion, how Karanavasayi Viṣṇu enters in the each universe. He's... Then He expands Himself as Kśīrodakaśāyī Viṣṇu. We are explaining that. Kṛṣṇa says in Bhagavad-gītā, viṣṭabhya. Viṣṭabhya means entering.
