True knowledge comes through hearing from authority, and dharma means serving Krishna as our eternal constitutional position.Listen — Srila Prabhupada Uvaca
Śrīmad-Bhāgavatam 6.1.40 — July 21, 1975, San Francisco 750721SB-SAN FRANCISCO [26:26 Minutes] SB-06.01.40_750721SB-SAN FRANCISCO Nitāi: [leads chanting of verse, etc.] yamadūtā ūcuḥ veda-praṇihito dharmo hy adharmas tad-viparyayaḥ vedo nārāyaṇaḥ sākṣāt svayambhūr iti śuśruma [SB 6.1.40] [break] [02:23] "The Yamadūtas replied: What is established by the Vedas as duty, that is called religious principles, and irreligion is the opposite of that. The Vedas are directly the Supreme Personality of Godhead, Nārāyaṇa, and are self-born. Thus we have heard from Yamarāja." Prabhupāda: yamadūtā ūcuḥ veda-praṇihito dharmo hy adharmas tad-viparyayaḥ vedo nārāyaṇaḥ sākṣāt svayambhūr iti śuśruma [SB 6.1.40] This word śuśruma is very important. "We have heard it." They never say that "We have manufactured it." Śuśruma means "We have heard it." Śuśrūṣā, śuśruma: "We have heard it with service." That is the way of Vedic instruction. The Bhagavad-gītā says, tad viddhi praṇipātena paripraśnena sevayā upadekṣyanti te jñānaṁ jñāninas tattva-darśinaḥ [Bg. 4.34] To receive Vedic knowledge...
Vedic knowledge means spiritual knowledge. Material knowledge also, the same process, any knowledge, especially spiritual knowledge. Because material things sometimes we can perceive directly because our body is material. But spiritual knowledge, unless you hear from the authority, there is no source of knowledge.
You cannot understand, because we do not see what is spirit. I am spirit, you are spirit, but I do not see your spirit soul, you do not see my spirit soul, because we have got material eyes. When somebody dies, one cries, "Oh, my father is gone. My father is gone." Where is your father gone?
Your father is lying on the bed. Why do you say father gone? That means with these material eyes we cannot see spirit. So these material eyes has to be purified. Then spiritual knowledge begins.
Therefore it is said, ajñāna-timirāndhasya jñānāñjana-śalākayā cakṣur unmīlitaṁ yena tasmai śrī-gurave namaḥ All of our eyes are covered with darkness; we cannot see. Then how we can see in the darkness? Ajñāna-timirāndhasya jñānāñjana-śalākayā. Śalākayā means torch. So the torch, what is that torch?
Jñānāñjana, smearing with the ointment of knowledge, that is the torch. So knowledge means not to see but to hear. Therefore it is called śruti, śuśruma. Knowledge has to be received through the ear, not by these eyes.
Not by the eyes. This is not recommended. Nobody says, "I want to see knowledge." No: "I want to hear knowledge." Therefore it is called śruti, and knowledge is received through the ear, aural reception. Why not with eyes and other senses? That is also very important to know.
