People should be trained up according to quality and work. There must be institution to train first-class men. There are first-class men, intellectuals. They should be trained up as brāhmaṇas. That is the system. Second-class men, they should be trained up as kṣatriyas. Third-class men, they should be trained up as vaiśyas. And fourth-class men, means below third-class, they should be engaged as śūdras, workers, and below them, caṇḍāla. That I have already explained. So nobody should be left alone. Everyone should be engaged. That is Kṛṣṇa consciousness. Everyone should be engaged in Kṛṣṇa consciousness business. Then there will be no unemployment.
First-class men, let them become scholars, philosophers, preachers, instructors, brahminical business. Paṭhana pāṭhana yajana yājana dāna pratigrahaḥ. These are the six businesses for the brāhmaṇa class. They should be highly educated, paṭhana, highly learned, and pāṭhana, and they should educate others also. But if he is not educated, how he will educate others? Paṭhana pāṭhana yajana yājana. He should be worshipper of the Supreme Lord, yajana, and yājana, he should instruct others also.
