You haven't got to speculate just like so many theosophists and philosophers and theologists who are trying to speculate to understand what is God. Why you are speculating, wasting your time? Why not take full knowledge here?

Bhagavad-gita As It Is Lectures

Simply try to understand and study Kṛṣṇa. And Kṛṣṇa is giving about Himself. You haven't got to speculate just like so many theosophists and philosophers and theologists, and they are trying to speculate to understand what is God. Why you are speculating, wasting your time? Why not take full knowledge here? Everything is ready.

Lecture on BG 7.3 -- London, March 11, 1975:

So in this way we have to understand Kṛṣṇa. Therefore Kṛṣṇa says, yatatām api siddhānāṁ kaścid vetti māṁ tattvataḥ (BG 7.3). What is Kṛṣṇa's position, how is Kṛṣṇa the Supreme Lord, how He is the supreme controller—we have to know these. Then our life is perfect. We must know our position, what is the perfection of life, what is Kṛṣṇa, and what is my relationship with Kṛṣṇa. In this way, if we understand, that is our perfect life. Kṛṣṇa is describing that. Because in this chapter He says, asaṁśayaṁ samagraṁ māṁ yathā jñāsyasi tac chṛṇu (BG 7.1). Kṛṣṇa is ready to give us instruction, asaṁśayam, without any doubt. Anyone who is advanced in Kṛṣṇa consciousness, ask him any question like this. He will give full answer, without any doubt. That is the perfection of life. We must know kṛṣṇa-tattva. The same thing I was explaining yesterday. Caitanya Mahāprabhu says, yei kṛṣṇa-tattva-vettā sei guru haya (CC Madhya 8.128). You try to understand Kṛṣṇa. Simply try to understand and study Kṛṣṇa. And Kṛṣṇa is giving about Himself. You haven't got to speculate just like so many theosophists and philosophers and theologists, and they are trying to speculate to understand what is God. Why you are speculating, wasting your time? Why not take full knowledge here? Everything is ready. No, that they will not take. They will speculate. So let them speculate. They will never be successful. But if you want success, you Kṛṣṇa conscious men, then you read Bhagavad-gītā thoroughly and understand and try to understand Kṛṣṇa perfectly. You'll understand because Kṛṣṇa is giving His own identity, identification, what He is. Then where is the difficulty? And if you understand Kṛṣṇa, you become perfect.
