SB Canto 3

The qualification, then, of a spiritual master is not to be a qualified brāhmaṇa, but to be well versed in the science of Kṛṣṇa.

SB 3.6.30, Purport:

An impersonalist can become a qualified brāhmaṇa, but he cannot become a spiritual master unless and until he is promoted to the stage of a Vaiṣṇava, or a devotee of the Personality of Godhead. Lord Caitanya, the great authority of Vedic wisdom in the modern age, stated:

kibā vipra, kibā nyāsī, śūdra kene naya

yei kṛṣṇa-tattva-vettā, sei 'guru' haya

A person may be a brāhmaṇa or a śūdra or a sannyāsī, but if he happens to be well versed in the science of Kṛṣṇa, then he is fit to become a spiritual master. (CC Madhya 8.128) The qualification, then, of a spiritual master is not to be a qualified brāhmaṇa, but to be well versed in the science of Kṛṣṇa.

One who is conversant with Vedic wisdom is a brāhmaṇa. And only a brāhmaṇa who is a pure Vaiṣṇava and knows all the intricacies of the science of Kṛṣṇa can become a spiritual master.
