Kaushītaki Upanishad. The third part consists of the remaining four sections of Book II., which form the regular Aitareya Upanishad. Finally, Book III. deals with the mystic and allegorical meaning of the three principal modes in which the Veda is recited in the Saṃhitā, Pada and Krama Pāṭhas, and of the various letters of the alphabet.
To the Kaushītaki Brāhmaṇa is attached the Kaushītaki Āraṇyaka . It consists of fifteen chapters. The first two of these correspond to Books I. and V. of the Aitareya Āraṇyaka, the seventh and eighth to Book III., while the intervening four chapters (3-6) form the Kaushītaki Upanishad. The latter is a long and very interesting Upanishad. It seems not improbably to have been added as an independent treatise to the completed Āraṇyaka, as it is not always found in the same part of the latter work in the manuscripts.
Brāhmaṇas belonging to two independent schools of the Sāmaveda have been preserved, those of the Tāṇḍins and of the Talavakāras or Jaiminīyas. Though several other works here claim the title of ritual text-books, only three are in reality Brāhmaṇas. The Brāhmaṇa of the Talavakāras, which for the most part is still unpublished, seems to consist of five books. The first three (unpublished) are mainly concerned with various parts of the sacrificial ceremonial. The fourth book, called the Upanishad Brāhmaṇa (probably "the Brāhmaṇa of mystic meanings"), besides all kinds of allegories of the Āraṇyaka order, two lists of teachers, a section about the origin of the vital airs (prāṇa) and about the sāvitrī stanza, contains the brief but important Kena Upanishad. Book V., entitled Ārsheya-Brāhmaṇa, is a short enumeration of the composers of the Sāmaveda.
