taiś cāpi sāmavedo 'sau śākhābhir bahulīkṛtaḥ

atharvavedaṃ sa muniḥ sumantur amitadyutiḥ //

YOU shall now hear, Maitreya, how Jaimini, the pupil of Vyása, divided the branches of the Sáma-veda. The son of Jaimini was Sumantu, and his son was Sukarman, who both studied the same Sanhitá under Jaimini. The latter composed the Sáhasra Sanhitá (or compilation of a thousand hymns, &c.), which he taught to two disciples, Hirańyanábha, also named Kauśalya (or of Kośala), and Paushyinji. Fifteen disciples of the latter were the authors of as many Sanhitás: they were called the northern chaunters of the Sáman. As many more, also the disciples of Hirańyanábha, were termed the eastern chaunters of the Sáman, founding an equal number of schools. Lokákshi, Kuthumi, Kushídí, and Lángali were the pupils of Paushyinji; and by them and their disciples many other branches were formed. Whilst another scholar of Hirańyanábha, named Kriti, taught twenty-four Sanhitás to as many pupils; and by them, again, was the Sáma-veda divided into numerous branches.

I will now give you an account of the Sanhitás of the Atharva-veda. The illustrious Muni Sumantu taught this Veda to his pupil Kabandha, who made it twofold, and communicated the two portions to Devaderśa and to Pathya. The disciples of Devaderśa were Maudga, Brahmabali, Śaulkáyani, and Pippaláda. Pathya had three pupils, Jájali, Kumudádi, and Śaunaka; and by all these were separate branches instituted. Śaunaka having divided his Sanhitá into two, gave one to Babhru, and the other to Saindhaváyana; and from them sprang two schools, the Saindhavas and Munjakeśas. The principal subjects of difference in the Sanhitás of the Atharva-veda are the five Kalpas or ceremonials: the Nakshatra Kalpa, or rules for worshipping the planets; the Vaitána Kalpa, or rules for oblations, according to the Vedas generally; the Sanhitá Kalpa, or rules for sacrifices, according to different schools; the Ángirasa Kalpa, incantations and prayers for the destruction of foes and the like; and the Sánti Kalpa, or prayers for averting evil.
