So tattva-darśī, one who has seen the truth, you have to accept him as guru. Tattva-darśī. Darśī means who has practical experience. Take, for example, just like Arjuna. Arjuna is directly receiving the knowledge from Kṛṣṇa. He's guru. What he said, we accept that. But if you accept somebody who wants to kill Kṛṣṇa and become himself Kṛṣṇa, he's a rascal. He's not guru. Because his policy is to accept the place of Kṛṣṇa, not to serve Him.
