SB Canto 3

The favor of the spiritual master is not received through any other part of the body but the ears.

SB 3.22.7, Purport:

Manu said that since he was advised and instructed by Kardama Muni, he was very much favored. He considered himself lucky to receive the message by aural reception. It is especially mentioned here that one should be very inquisitive to hear with open ears from the authorized source of the bona fide spiritual master. How is one to receive? One should receive the transcendental message by aural reception. The word karṇa-randhraiḥ means "through the holes of the ears." The favor of the spiritual master is not received through any other part of the body but the ears. This does not mean, however, that the spiritual master gives a particular type of mantra through the ears in exchange for some dollars and if the man meditates on that he achieves perfection and becomes God within six months. Such reception through the ears is bogus. The real fact is that a bona fide spiritual master knows the nature of a particular man and what sort of duties he can perform in Kṛṣṇa consciousness, and he instructs him in that way. He instructs him through the ear, not privately, but publicly. "You are fit for such and such work in Kṛṣṇa consciousness. You can act in this way." One person is advised to act in Kṛṣṇa consciousness by working in the Deities' room, another is advised to act in Kṛṣṇa consciousness by performing editorial work, another is advised to do preaching work, and another is advised to carry out Kṛṣṇa consciousness in the cooking department.
