The chief Grihya Sutra of the Samaveda is that of Gobhila, which is one of the oldest, completest, and most interesting works of this class. Its seems to have been used by both the schools of its Veda. Besides the text of the Samaveda it presupposes the Mantra Brahmana. The latter is a collection, in the ritual order, of the mantras (except those occurring in the Samaveda itself), which are quoted by Gobhila in an abbreviated form. The Grihya Sutra of Khadira, belonging to the Drahyayana school and used by the Ranayaniya branch of the Samaveda, is little more than Gobhila remodelled in a more succinct form. The Grihya Sutra of the White Yajurveda is that of Paraskara, also called the Katiya or Vajasaneya Grihya Sutra. It is so closely connected with the Çrauta Sutra of Katyayana, that it is often quoted under the name of that author. The later law-book of Yajnavalkya bears evidence of the influence of Paraskara's work. Of the seven Grihya Sutras of the Black Yajurveda only three have as yet been published. The Grihya of Apastamba forms two books (26-27) of his Kalpa Sutra. The first of these two books is the Mantrapatha, which is a collection of the formulas accompanying the ceremonies. The Grihya Sutra, in the strict sense, is the second book, which presupposes the Mantrapatha. Books XIX. and XX. of Hiranyakeçin's Kalpa Sutra form his Grihya Sutra. About Baudhayana's Grihya not much is known, still less about that of Bharadvaja. The Manava Grihya Sutra is closely connected with the Çrauta, repeating many of the statements of the latter verbally. It is interesting as containing a ceremony unknown to other Grihya Sutras, the worship of the Vinayakas. The passage reappears in a versified form in Yajnavalkya's law-book, where the four Vinayakas are transformed into the one Vinayaka, the god Ganeça. With the Manava is clearly connected the Kathaka Grihya Sutra, not only in the principle of its arrangement, but even in the wording of many passages. It is nearly related to the law-book of Vishnu. The Vaikhanasa Grihya Sutra is an extensive work bearing traces of a late origin, and partly treating of subjects otherwise relegated to works of a supplementary character. To the Atharva-veda belongs the important Kauçika Sutra. It is not a mere Grihya Sutra, for besides giving the more important rules of the domestic ritual, it deals with the magical and other practices specially connected with its Veda. By its extensive references to these subjects it supplies much material unknown to other Vedic schools. It is a composite work, apparently made up of four or five different treatises. In combination with the Atharva-veda it supplies an almost complete picture of the ordinary life of the Vedic Indian.
