To the school of the Tandins belongs the Panchavimça ("twenty-five fold"), also called Tandya or Praudha, Brahmana, which, as the first name implies, consists of twenty-five books. It is concerned with the Soma sacrifices in general, ranging from the minor offerings to those which lasted a hundred days, or even several years. Besides many legends, it contains a minute description of sacrifices performed on the Sarasvati and Drishadvati. Though Kurukshetra is known to it, other geographical data which it contains point to the home of this Brahmana having lain farther east. Noteworthy among its contents are the so-called Vratya-Stomas, which are sacrifices meant to enable Aryan but non-Brahmanical Indians to enter the Brahmanical order. A point of interest in this Brahmana is the bitter hostility which it displays towards the school of the Kaushitakins. The Shadvimça Brahmana, though nominally an independent work, is in reality a supplement to the Panchavimça, of which, as its name implies, it forms the twenty-sixth book. The last of its six chapters is called the Adbhuta Brahmana, which is intended to obviate the evil effects of various extraordinary events or portents. Among such phenomena are mentioned images of the gods when they laugh, cry, sing, dance, perspire, crack, and so forth. The other Brahmana of this school, the Chhandogya Brahmana, is only to a slight extent a ritual text-book. It does not deal with the Soma sacrifice at all, but only with ceremonies relating to birth and marriage or prayers addressed to divine beings. These are the contents of only the first two "lessons" of this Brahmana of the Sama theologians. The remaining eight lessons constitute the Chhandogya Upanishad. There are four other short works which, though bearing the name, are not really Brahmanas. These are the Samavidhana Brahmana, a treatise on the employment of chants for all kinds of superstitious purposes; the Devatadhyaya Brahmana, containing some statements about the deities of the various chants of the Samaveda; the Vamça Brahmana, which furnishes a genealogy of the teachers of the Samaveda; and, finally, the Samhitopanishad, which, like the third book of the Aitareya Aranyaka, treats of the way in which the Veda should be recited. The Brahmanas of the Samaveda are distinguished by the exaggerated and fantastic character of their mystical speculations. A prominent feature in them is the constant identification of various kinds of Samans or chants with all kinds of terrestrial and celestial objects. At the same time they contain much matter that is interesting from a historical point of view.
