Śyāmasundara: Actually, he is just exploring this possibility, that because we can't know it by our senses therefore we must...
Prabhupāda: That is misleading. Nobody can ascertain in that way. That is not possible. In the śāstras it is said that panthās tu koṭi-śata-vatsara-sampragamya. He is thinking he is a man living for fifty or sixty or a hundred years. But if somebody is there, just like modern, these sputnik scientists, they say that if one can go forty thousands of years at the speed of light, he can approach the topmost planet. So śāstra says even one goes forty thousands of years, still you won't find where is Kṛṣṇa, where is Kṛṣṇa's abode. Not only at the speed of light, but he says the speed of mind and air. Panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi manaso muni-puṅgavānām: (Bs. 5.34) still, the subject matter which is beyond my senses will remain the same, beyond my senses. This material attempt will not help. Never. There is another verse that adhane gopī chindan vidhena ataḥ pudedevo padamjadayan (?): "Dear Lord, a devotee who has got a little grace from your lotus feet, padamjadaya (?), he can understand You. Others, they may speculate for millions of years. Still it is not possible." Just like Kṛṣṇa says that manuṣyāṇāṁ sahasreṣu: (BG 7.3) "Out of many millions of people, one is interested to make his life successful, and out of millions of successful..." Successful means one who understands that I am not this body. You ask, you take census, in this Nairobi city, you will find that 99.9%, or more than that, people do not know what he is. Everyone knows that "I am this body." So perfection of life means one who understands that "I am not this body..." They become impersonalists, something like that, or voidists. Out of them—those who have understood perfection, that "I am not this body"—one can understand Kṛṣṇa. Out of many thousands of people who have attained actual perfect. So this Kṛṣṇa consciousness is actually not so easy, but these devotees are actually realizing Kṛṣṇa. Why? By the grace of Kṛṣṇa. Because the devotees are engaged in His service, He is revealing Himself. That is the process. Not by this, Kant's speculation. It is not possible.
