Devotees see God always in their hearts; atheists see Him only in death, when everything is taken away.Listen — Srila Prabhupada Uvaca
Nṛsiṁha-caturdaśī Lord Nṛsiṁha-deva's Appearance Day — May 1, 1969, Boston 690501NA-BOSTON [15:41 Minutes] NrsimhaDevaApp_690501NA-BOSTON Prabhupāda: ...just like Janmāṣṭamī and Nandotsava. Yesterday you had some festival? No. That's all right. So Nṛsiṁha-deva has appeared to convince the atheist [laughter] that there is no God.
[chuckles] 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?
Prahlāda Mahārāja was seeing always, constantly, Nṛsiṁha-deva. Mahābhāgavata. Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti [Bs. 5.38]. [I worship Govinda, the primeval Lord, who is Śyāmasundara, Kṛṣṇa Himself with inconceivable innumerable attributes, whom the pure devotees see in their heart of hearts with the eye of devotion tinged with the salve of love.] Those who have developed love of God, prema, premāñjana-cchurita... When one's eyes are anointed with the..., what is called? Viṣṇujana: Salve.
Satsvarūpa: Ointment. Prabhupāda: No, no. There is a technical name. Kajal? Brahmānanda: Make-up? Prabhupāda: Yes. Devotee: Mascara? Prabhupāda: Huh? Anyway, 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. God is not invisible. Simply just like a man with cataract or any other eye disease, he cannot see. That does not mean the things are not existing.
He cannot see. God is there, but because my eyes are not competent to see God, therefore I deny God. God is there everywhere. So in the material condition of our life, our eyes are blunt. Not only eyes; every sense, especially eyes.
Because we are very proud of our eyes, and we say, "Can you show me God?" You see. But he does not think that whether his eyes are competent to see God. That is atheism. He does not consider his position, "In what position I am?" Even one cannot see a big man like President Nixon, and he wants to see God without qualification.
