I am training these European and American boys, most of them coming from Christian and Jewish families, and they are accepting to become a pure brahmana and then a pure sannyasi. This system should be introduced. They must sit for proper examination after being trained. And then why not accept them as real brahmana by quality and work? This procedure is recommended both in the Bhagavad-gita and in the Srimad-bhagavatam. In the Bhagavad-gita, it is said that the brahmana, ksatriya, vaisya, sudra should be selected by quality and work. Similarly, in the Srimad-bhagavatam, it is said that if quality and work is present in a different varna, that is to say, if the quality of a brahmana is visible in a person born in sudra family, such person on account of quality and work, should be accepted as brahmana.
