The Supreme Personality of Godhead is speaking Himself.
So He was speaking to Arjuna. So He says the process, how to understand God. The process is, means:
- mayy āsakta-manāḥ pārtha
- yogaṁ yuñjan mad-āśrayaḥ
- asaṁśayaṁ samagraṁ māṁ
- yathā jñāsyasi tac chṛṇu
- (BG 7.1)
Kṛṣṇa, the Supreme Personality of Godhead, says that "If you want to know Me, then you have to increase your attachment for Me." This is the first condition. Mayy āsakta. Mayi āsakta-manāḥ. Our mind is attracted by so many things, especially in the material world. When yoga system was advised to Arjuna that "You concentrate your mind upon Me," Arjuna flatly declined, "My dear Kṛṣṇa, I cannot concentrate my mind in any particular thing." But he said that "I have got my mind on You." That is different thing. "But if you ask me to concentrate, it is very difficult for me."
