The word gotrajaḥ is significant in this connection. Brāhmaṇas generally act as spiritual masters of two dynasties. One is their disciplic succession, and the other is the dynasty born of their semen. Both descendants belong to the same gotra, or dynasty. In the Vedic system we sometimes find that both brāhmaṇas and kṣatriyas and even vaiśyas come in the disciplic succession of the same ṛṣis. Because the gotra and dynasty are one, there is no difference between the disciples and the family born of the semen. The same system still prevails in Indian society, especially in regard to marriage, for which the gotra is calculated. Here the word gotrajaḥ refers to those born in the same dynasty, whether they be disciples or members of the family.
