Guest: There is some our ācāryas. How about Christ or Muhammad and Zarathustra, all these people?
Prabhupāda: They accept God, that's all. But God is here explained. They cannot give an explicit idea of God. But here is God speaking personally. They have got "There is God," "God is great." That's nice. But who is that God, how He is great, that they have to learn further. Simply a vague idea, that "God is great..." One should know how He is great and who is that great. That is perfection. So that is explained here. They accept God. That is... They are also our brother because they accept God. They are not atheist. Atheists, they don't accept God. "There is no God"—that is atheist. But here they are theist. They accept God. They want to please God. They go to the church, go to the mosque, offer prayer. Prayer is also bhakti, devotional service. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇaṁ pāda-sevanam, arcanaṁ vandanaṁ dāsyaṁ... (SB 7.5.23). Śravanaṁ kīrtanaṁ viṣṇoḥ smaraṇam..., arcanaṁ vandanam. Vandanam. The Christian way or the Muslim way, to offer... The Muslim offer obeisances and offer prayer. So that is also bhakti. The Christian also do that, so that is also bhakti. And they accept God; we accept God. So there is no difference. But the only point is who is that God.
Guest: They accept as supreme power.
Prabhupāda: No, supreme power must be that... Behind the power there must be powerful.
Guest: They say powerful but what about...
Prabhupāda: Yes, then we have to know this powerful, not only the power. That is stated in the Bhagavad-gītā. Mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10). In another place, sṛṣṭi-sthiti-pralaya-sādhana-śaktir eka chāyeva yasya bhuvanāni bibharti durgā (Bs. 5.44). Durgā is power. Power is in... What kind of power? Sṛṣṭi-sthiti-pralaya-sādhana-śaktir eka. She can create, she can maintain and she can destroy, so powerful. But this power, sṛṣṭi-sthiti-pralaya-sādhana-śaktir eka chāyeva (Bs. 5.44), is working just like shadow. Just like here is shadow. I am moving this hand; the shadow is moving. Shadow is not independently moving. Therefore this gigantic power, material energy, is working under the direction of Kṛṣṇa. That is stated in the Bhagavad-gītā, mayādhyakṣeṇa: (BG 9.10) "under My superintendence." So we are allured with the power, but who is manipulating this power we do not know. That is God.
Guest: Well, sir, this is a point which I really fail to understand because...
Prabhupāda: But that is everyone's dilemma, that "What is this power?" The scientists, the (sic:) physists, they are seeing the power. The power is working and energy is working. But how it is working, that is further enquiry.
