Prabhupada's lecture - Śrīmad-Bhāgavatam 1.15.42 - Los Angeles, December 18, 1973
There is a small story. Perhaps I have narrated this story sometimes ago, that in a school... Formerly there was no charge for school. Now everything has become business. Formerly a brāhmaṇa, he'll start a school. Brāhmaṇa is paṭhana pāṭhana. His business is to become learned himself and to distribute his knowledge, education, to everyone free. This is brāhmaṇa. The brāhmaṇa, and the opposite word is kṛpaṇa. Kṛpaṇa means miser. A miser, he has got money, but he does not spend. He keeps it only. And brāhmaṇa means he has got knowledge and he distributes for others' benefit. That is brāhmaṇa.
Therefore we are making every one of our disciples brāhmaṇa, not that he should simply know himself what is God. No. He must distribute the knowledge also. Go from town to town, village to village, and try to convince these rascals what is God. They simply write, "In God We Trust," but they do not know what is God or how to trust, nothing. Now let them know it scientifically. Here is the movement, Kṛṣṇa consciousness movement. What is this movement? To know God. Of course, we cannot know God perfectly. God is so unlimited. Still, as far as possible, we can know, as God speaks Himself in the Bhagavad-gītā.
