Los Angeles, August 13, 1972
Therefore a devotee is not allured by any of the opulences of this material world. They are not interested. They are interested to transfer themselves in the spiritual world where, it is stated in the Bhagavad-gītā, yad gatvā na nivartante tad dhāma paramaṁ mama [Bg. 15.6]. That sphere, that sky, where going, nobody comes back to this sky... This is material sky, and there is spiritual sky. These informations are there. If you accept it, then it is all right. But if you..., even if you don't accept it, that is also all right, because we take Vedic version as absolute truth. So these informations are there and they have been accepted by great ācāryas. Not that we are simply accepting. Great ācāryas. Just like Vyāsadeva, Nārada, Asita, and modern age Śrī Rāmānuja, Śrī Madhvācārya, Śrī Caitanya. They are great scholars. They're great, expert in the spiritual science.
They have accepted. And we accept Kṛṣṇa, the Supreme Personality of Godhead, by His activities, by the definition of possessing all the six opulences. We don't accept anybody, an ordinary man... Just like now it is a fashion. Everybody comes and says, "I am God." No. We don't accept in that way. Arjuna was talking with Kṛṣṇa. He knew that Kṛṣṇa is the Supreme Personality of Godhead, but, in order to convince us that in future there may not be any misunderstanding about the Supreme Personality of Godhead, he requested Kṛṣṇa to show His universal form. So He showed him. So there is no doubt about, about Kṛṣṇa, the Supreme Personality of Godhead.
