Srimad-Bhagavatam Lectures

Brāhmaṇa means that he must have full knowledge and he must distribute the knowledge, not that keep it for himself, reserved: "Nobody should know it.".

Lecture on SB 1.8.21 -- Mayapura, October 1, 1974:

The brāhmaṇa, their duty is how to practice to control the mind, to control the senses, śamo damas titikṣā, to be tolerant, to be very simple, simple living, not very gorgeous living. Whatever is absolutely necessary, a brāhmaṇa will accept, not more than that. That is simplicity, simple living, high thinking. So this is brāhmaṇa's... Śamo damas titikṣā ārjavam. And then jñānam. Jñānam means to understand what is what. People are all in ignorance rascals. The brāhmaṇa should not be rascal. Therefore brāhmaṇa is given the title paṇḍita. Still in India they say, brāhmaṇa-paṇḍita. Brāhmaṇa must be a paṇḍita, a learned. A brāhmaṇa rascal is not brāhmaṇa. You are... "What you are?" "I am brāhmaṇa." "What do you do?" "Now, I pull ṭhelā." So that is not brāhmaṇa. Brāhmaṇa means paṇḍita. He must be a learned man. Paṭhana-pāṭhana yajana-yājana dāna-pratigraha. These are the brāhmaṇa's occupational duty. He must be learned scholar himself, and he would try to make others also learned scholar, paṭhana-pāṭhana, not that "I know." If you know something better, means very valuable, you must distribute it. Otherwise, in Sanskrit language they are called jñāna-khala: "miser in knowledge." One who has got knowledge... Just like in the modern world, if one is scientifically advanced, he gives the knowledge to others. He goes from university to university and speaks about the new invention. So similarly, brāhmaṇa means that he must have full knowledge and he must distribute the knowledge, not that keep it for himself, reserved: "Nobody should know it." No. Paṭhana-pāṭhana. So jñānaṁ vijñānam.
