3.6.2

sumantus tasya putro 'bhūt sukarmāsyāpy abhūt sutaḥ
adhītavantāv ekaikāṃ saṃhitāṃ tau mahāmunī //

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.
