Nrsimha-deva has appeared to convince the atheist (laughter) that there is no [sic] God. This is a lying propaganda that nobody has seen God. Everyone has seen God. The devotee sees within his heart, in the temple, and everywhere. And the atheist sees when he’s… when the clock, the handles in the clock are over. You see? Prahlada Maharaja was seeing always, constantly Nrsimha-deva. Mahabhagavata. Premanjana-cchurita-bhakti-vilocanena santah sadaiva hrdayesu vilokayanti [Bs. 5.38]. Those who have developed love of God, prema, premanjana-cchurita… When one’s eyes are anointed with the ointment which is applied to the eyes for clear vision. So when the ointment of love of Godhead will be applied in our eyes, then with these eyes we shall be able to see God.
