Bhāgavata says that vadanti tat tattva-vidas tattvam (SB 1.2.11). "The Absolute knowledge, the Absolute Truth, is nondual." How it is nondual? That brahmeti paramātmeti bhagavān iti śabdyate. You either you realize the Absolute Truth as impersonal Brahman or localized Paramātmā, Supersoul, or as the Supreme Personality of Godhead, Kṛṣṇa or Viṣṇu; they are one and the same. How one and the same? That is also explained.
So God realization, it is said in the Vedic literature, that avāṅ-manasā-gocaraḥ. It is very difficult to realize God. He is beyond our mental speculational field, or He is beyond our conception, beyond our words. But there is other verses also that, athāpi te deva padāmbuja-dvaya-prasāda-leśānugṛhīta eva hi, jānāti tattvam (SB 10.14.29). One can understand what is God by the mercy of God, not by mental speculation. It is not possible. We have got very limited scope of knowledge. Our senses are imperfect, we are full of cheating propensities, and we are liable to commit mistake. These four defects are within us.
However a great man one may be, he is sure to commit mistake. I shall give you one tangible example in the life of Mahatma Gandhi. You know he was a very great man, political leader in India. So he was also very God-fearing man, a very nice soul. But he also committed mistakes so many times.
So to err is human. This is a fact in every person. Therefore, because we commit mistake, because we are sometimes illusioned, and because we have got a propensity of cheating others, and because our senses are imperfect, therefore, simply by mental speculation it is not possible to realize God.
Then how one can realize God? That is mentioned in the Bhagavad-gītā and other literature, that by the mercy of God one can realize God. So by His causeless mercy, He comes down. Yadā yadā hi dharmasya glānir bhavati bhārata (BG 4.7), it is stated in the Bhagavad-gītā.
So Lord Kṛṣṇa is accepted as the Supreme Personality of Godhead at least by the great ācāryas of India. Even, as I was speaking of Śaṅkarācārya, he was impersonalist, but still he has admitted in his commentary on Śrīmad-Bhāgavatam that sa kṛṣṇa bhagavān svayam. He has accepted it.
In the beginning of his commentary he says, nārāyaṇaḥ para avyaktāt: "Nārāyaṇa, the Supreme Personality of Godhead, is beyond this material creation." And in next page he has admitted, "That Supreme Personality of Godhead Nārāyaṇa is Kṛṣṇa, who is born as the son of Devakī and Vasudeva."
So, so far Indian scholars . . . I don't speak of modern scholars. Those who are authorized scholars of bygone ages, admitted by the Vedic society—Śaṅkarācārya, Rāmānujācārya and Viṣṇu Svāmī, Nimbārka and their followers. And there are many hundreds and thousand temples of Kṛṣṇa, Viṣṇu, in India. If you have ever gone, you might have seen.
In Vṛndāvana, only a small city of fifty thousand people, there are five thousand Kṛṣṇa temple. So this Kṛṣṇa consciousness movement is very strong and very old in India. And if you also accept this, without any loss on your part, you will be happy. You will be happy. That is the process of peace.
