Externally he heard—somewhere the sound came—and internally He confirmed, "Yes." So Kṛṣṇa is helping us externally by the spiritual master, internally by instruction. Buddhi-yogaṁ dadāmi (BG 10.10). In this way, He is trying to help us. Unfortunately we do not care to take His help. Then why should we not suffer?
Antar-bahiḥ. Antar-bahiḥ. There are two things: inside and outside. So Kṛṣṇa is . . . outside He is helping, spiritual master. Spiritual master is external manifestation of the Supreme Lord. Just like if somebody is going somewhere in this Tokyo city, I have to say something, so I apply him, "Will you kindly carry this message to him?"
Similarly, Kṛṣṇa deputes some of His confidential devotees to help the people to become Kṛṣṇa conscious: "Please go and tell him this." The spiritual master is, therefore, external manifestation of the Supreme Lord. And internally He is sitting there as Paramātmā. So both ways, He is helping. And because the business is Kṛṣṇa consciousness, therefore there is no difference between the external teacher and the internal teacher. Because the teaching is the same.
