Hindu gotras
There are 49 established Hindu gotras. All members of a particular gotra are believed to possess certain common characteristics by way of nature or profession. Many theories have been propounded to explain this system. According to the brahminical theory, the Brahmins are the direct descendants of seven or eight sages who are believed to be the mind-born sons of Brahma. They are Gautama, Bharadvaja, Vishvamitra, Jamadagni, Vashista, Kashyapa and Atri. To this list, Agasthya is also sometimes added. These eight sages are called gotrakarins from whom all the 49 gotras (especially of the Brahmins) have evolved. For instance, from Atri sprang the Atreya and Gavisthiras gotras.
A gotra must be distinguished from a kula. A kula is a set of people following similar cultural rituals, often worshiping the same divinity (the Kula-Devata, god of the clan). Kula does not relate to lineage or caste. In fact, it is possible to change one's kula, based on one's faith.
