6 Kṛṣṇa Consciousness: the Topmost Yoga System
or our time, because we are in full faith that Kṛṣṇa is the Supreme Personality of Godhead. Theoretically or practically, you should accept Kṛṣṇa as the Supreme Person. Theoretically, there is the revealed scripture. You will understand from the Vedic literature, from the great devotees in the past and in the present.
For the present, there is Lord Caitanya. Lord Caitanya is the great authority. None is greater. He was mad after Kṛṣṇa. And then, after Him, His six disciples, the  gosvāmīs , have left us an immensely valuable literature—especially Jīva Gosvāmī. They have written volumes on Kṛṣṇa. So, under disciplic succession, we have come to this point; and if you like past history, then go back a long, long time to Vyāsadeva. He is known to have written the  Śrīmad-Bhāgavatam  and other literature on Kṛṣṇa.  Śrīmad-Bhāgavatam  is nothing but a description of Kṛṣṇa. Vyāsa is also the writer of the  Bhagavad-gītā . The  Gītā  was spoken by Kṛṣṇa and noted down by Vyāsa, who put this  Gītā  into the  Mahābhārata .
So Vyāsadeva accepts Kṛṣṇa as the Supreme Person. In the  Śrīmad-Bhāgavatam  he has given the description of the different incarnations; there are twenty-five of Them. And, in the conclusion, he says that the descriptions that are given of different incarnations are all parts of the representations of God. But Kṛṣṇa is the Supreme Personality of Godhead Himself. He is not part, but one hundred percent—one hundred percent God. So there is the evidence of authority.
And, practically, if we believe the  śāstras , the scriptures, then we can see: Who can be more powerful than Kṛṣṇa? Who can be more beautiful than Kṛṣṇa? Who can be more famous than Kṛṣṇa? Kṛṣṇa appeared five thousand years ago, but His knowledge, which He gave in the form of the  Śrīmad Bhagavad-gītā , is still worshiped. It is worshiped not only by the Hindus or the Indians, but is read all over the world. In your country there are at least fifty different editions of the  Bhagavad-gītā ,
