The religion of the Yajurveda may be described as a kind of mechanical sacerdotalism. A crowd of priests conducts a vast and complicated system of external ceremonies, to which symbolical significance is attributed, and to the smallest minutiæ of which the greatest weight is attached. In this stifling atmosphere of perpetual sacrifice and ritual, the truly religious spirit of the Rigveda could not possibly survive. Adoration of the power and beneficence of the gods, as well as the consciousness of guilt, is entirely lacking, every prayer being coupled with some particular rite and aiming solely at securing material advantages. As a natural result, the formulas of the Yajurveda are full of dreary repetitions or variations of the same idea, and abound with half or wholly unintelligible interjections, particularly the syllable om. The following quotation from the Maitrāyaṇī Saṃhitā is a good example: Nidhāyo vā nidhāyo vā oṃ vā oṃ vā oṃ vā ē ai oṃ svarṇajyotiḥ. Here only the last word, which means “golden light,” is translatable.

Thus the ritual could not fail to become more and more of a mystery to all who did not belong to the Brahman caste. To its formulas, no less than to the sacrifice itself, control over Nature as well as the supernatural powers is attributed. Thus there are certain formulas for the obtainment of victory; by means of these, it is said, Indra constantly vanquished the demons. Again, we learn that, if the priest pronounces a formula for rain while mixing a certain offering, he causes the rain to stream down. Hence the formulas are regarded as having a kind of magical effect by exercising compulsion. Similar miraculous powers later came to be attached to penance and asceticism among the Brahmans, and to holiness among the Buddhists. The formulas of the Yajurveda have not, as a rule, the form of prayers addressed to the gods, but on the whole and characteristically consist of statements about the result of employing particular rites and mantras. Together with the corresponding ritual they furnish a complex mass of appliances ready to hand for the obtainment of material welfare in general as well as all sorts of special objects, such as cattle or a village. The presence of a priest capable of using the necessary forms correctly is of course always presupposed. The desires which several rites are meant to fulfil amount to nothing more than childish absurdity. Thus some of them aim at the obtainment of the year. Formulas to secure possession of the moon would have had equal practical value.

Hand in hand with the elaboration of the sacrificial ceremonial went the growth and consolidation of the caste system, in which the Brahmans secured the social as well as the religious supremacy, and which has held India enchained for more than two thousand five hundred years. Not only do we find the four castes firmly established as the main divisions of Indian society in the Yajurveda, but, as one of the later books of the Vājasaneyi Saṃhitā shows, most of the mixed castes known in later times are already found to exist. The social as well as the religious conditions of the Indian people, therefore, now wear an aspect essentially differing from those revealed to us in the hymns of the Rigveda.

The Rig-, Sāma-, 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 Gṛihya Sūtras 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 Saṃhitās. 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 Paippalādas 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 “Paippalāda Mantras” mentioned in one of the Pariçishṭas or supplementary writings of the Atharva-veda.

The printed text, edited by Roth and Whitney in 1856, gives the recension of the Çaunaka school. Nearly the whole of Sāyaṇa’s commentary to the Atharva-veda has been edited in India. Its chief interest lies in the large number of readings supplied by it which differ from those of the printed edition of this Veda.

This Saṃhitā is divided into twenty books, containing 730 hymns and about 6000 stanzas. Some 1200 of the latter are derived from the Rigveda, chiefly from the tenth, first, and eighth books, a few also from each of the other books. Of the 143 hymns of Book XX., all but twelve are taken bodily from the established text of the Rigveda without any change. The matter borrowed from the Rigveda in the other books shows considerable varieties of reading, but these, as in the other Saṃhitās, are of inferior value compared with the text of the Rigveda. As is the case in the Yajurveda, a considerable part of the Atharva (about one-sixth) consists of prose. Upwards of fifty hymns, comprising the whole of the fifteenth and sixteenth, besides some thirty hymns scattered in the other books, are entirely unmetrical. Parts or single stanzas of over a hundred other hymns are of a similar character.

That the Atharva-veda originally consisted of its first thirteen books only is shown both by its arrangement and by its subject-matter. The contents of Books I.–VII. are distributed according to the number of stanzas contained in the hymns. In Book I. they have on the average four stanzas, in II. five, in III. six, in IV. seven, in V. eight to eighteen, in VI. three; and in VII. about half the hymns have only one stanza each. Books VIII.–XIII. contain longer pieces. The contents of all these thirteen books are indiscriminately intermingled.

The following five books, on the contrary, are arranged according to uniformity of subject-matter. Book XIV. contains the stanzas relating to the wedding rite, which consist largely of mantras from the tenth book of the Rigveda. Book XV. is a glorification of the Supreme Being under the name of Vrātya, while XVI. and XVII. contain certain conjurations. The whole of XV. and nearly the whole of XVI., moreover, are composed in prose of the type found in the Brāhmaṇas. Both XVI. and XVII. are very short, the former containing nine hymns occupying four printed pages, the latter consisting of only a single hymn, which extends to little more than two pages. Book XVIII. deals with burial and the Manes. Like XIV., it derives most of its stanzas from the tenth book of the Rigveda. Both these books are, therefore, not specifically Atharvan in character.
