The Rig-, Sama-, and Yajur-vedas alone were originally recognised as canonical collections. For they only were concerned with the great sacrificial ceremonial. The Atharva-veda, with the exception of the last book, which was obviously added in order to connect it with that ceremonial, is essentially unconnected with it. The ceremonial to which its hymns were practically applied is, with few exceptions, that with which the Grihya Sutras deal, being domestic rites such as those of birth, marriage, and death, or the political rites relating to the inauguration of kings. Taken as a whole, it is a heterogeneous collection of spells. Its most salient teaching is sorcery, for it is mainly directed against hostile agencies, such as diseases, noxious animals, demons, wizards, foes, oppressors of Brahmans. But it also contains many spells of an auspicious character, such as charms to secure harmony in family and village life, reconciliation of enemies, long life, health, and prosperity, besides prayers for protection on journeys, and for luck in gambling. Thus it has a double aspect, being meant to appease and bless as well as to curse. In its main contents the Atharva-veda is more superstitious than the Rigveda. For it does not represent the more advanced religious beliefs of the priestly class, but is a collection of the most popular spells current among the masses, who always preserve more primitive notions with regard to demoniac powers. The spirit which breathes in it is that of a prehistoric age. A few of its actual charms probably date with little modification from the Indo-European period; for, as Adalbert Kuhn has shown, some of its spells for curing bodily ailments agree in purpose and content, as well as to some extent even in form, with certain old German, Lettic, and Russian charms. But with regard to the higher religious ideas relating to the gods, it represents a more recent and advanced stage than the Rigveda. It contains, indeed, more theosophic matter than any of the other Samhitas. For the history of civilisation it is on the whole more interesting and important than the Rigveda itself. The Atharva-veda is extant in the recensions of two different schools. That of the Paippaladas is, however, known in a single birch-bark manuscript, which is ancient but inaccurate and mostly unaccented. It was discovered by Professor Bühler in Kashmir, and has been described by Professor Roth in his tract Der Atharvaveda in Kaschmir (1875). It will probably soon be accessible to scholars in the form of a photographic reproduction published by Professor Bloomfield. This recension is doubtless meant by the "Paippalada Mantras" mentioned in one of the Pariçishtas or supplementary writings of the Atharva-veda.
