"The first-class yogi is he who is always seeing Me within his heart." Yoginām api sarveṣāṁ. There are different types of yogis. The first-class yogi is he who can see Kṛṣṇa within his heart constantly, without any cessation. Smartavyaṁ satato viṣṇuḥ vismārtavyaṁ na jātucit. This is the process. One has to observe Viṣṇu within the heart always. Smartavyaṁ satato viṣṇuḥ vismartavyam na... This is Kṛṣṇa consciousness. One has to think of Kṛṣṇa or see Kṛṣṇa within the heart twenty-four hours. That is perfection of yoga. Yoginām api sarveṣāṁ mad-gatena āntarātmanā.
But the atheist class of men, they do not see. They do not like to see. Just like Hiraṇyakaśipu and Prahlāda. Prahlāda is the son of Hiraṇyakaśipu; a great devotee. And the father is atheist. That is the struggle. This struggle between the atheist and theist, always existing. But God, Hiraṇya, I mean to say, Nṛsiṁha-deva appeared. Nṛsiṁha-deva appeared for the solace of the devotee, Prahlāda, and for the death of the atheist. Both of them saw. Prahlāda saw Nṛsiṁha-deva as the most worshipable Deity, and Hiraṇyakaśipu saw the same person as death. Therefore God can be seen by everyone, atheist or theist, but they see in a different way. The, the theist, the devotee, sees God... Just like these devotees are worshiping the Lord, Kṛṣṇa, that "Here is Kṛṣṇa, Rādhārāṇī, and let us offer Him respect by offering ārātrika, prasādam." They're seeing also. The atheist will say, "What this nonsense? Some idol they are worshiping." The atheist will see, "What is this non...?" But that atheist will see God at the time of death, when He'll come as Nṛsiṁha-deva: immediately finished.
