Talk:The Vedas:The Four Vedas

By Sri Chandrasekharendra Saraswati Swami

The Vedas are traditionally regarded as ananta (endless). Although only a small portion of this infinite body of knowledge was revealed to the ṛṣi-s, that revealed corpus is considered sufficient for the spiritual and worldly welfare of human beings. Traditional thought maintains that complete knowledge of the Vedas belongs only to Brahmā, whereas human beings require only that portion necessary for the fulfilment of dharma and spiritual progress.

Each of the four Vedas exists in multiple recensions (śākhā-s), each preserving its own textual arrangement and oral tradition. These recensions may differ in the sequence of mantras, the inclusion of particular sūkta-s, or other textual features, while remaining part of the same Vedic tradition. The various śākhā-s are compared to the branches of a great tree, each belonging to one of the four Vedas: the Ṛgveda, Yajurveda, Sāmaveda, or Atharvaveda.

Modern Indological scholarship has often proposed a chronological development of the Vedas, suggesting that the Ṛgveda preceded the Yajurveda and the remaining Vedas. Traditional Hindu thought, however, rejects this historical sequencing. According to the Śāstra-s, all four Vedas are eternal (apauruṣeya) and exist simultaneously as integral components of the cosmic order. Since the Vedas are held to transcend historical time and were perceived by ṛṣi-s endowed with extraordinary insight, attempts to assign chronological dates to the Vedas or to their constituent sections are regarded within the tradition as inappropriate.

Traditional literature further notes that references to the Yajurveda and Sāmaveda occur within the Ṛgveda itself. The Puruṣasūkta (Ṛgveda 10.90), for example, refers to the other Vedas, which is interpreted within the traditional framework as evidence that all four Vedas were always coexistent rather than products of successive historical periods.

Each Vedic recension traditionally comprises three principal components: the Saṃhitā, the Brāhmaṇa, and the Āraṇyaka. In common usage, however, the term "Veda" often refers specifically to the Saṃhitā, which forms the foundation of every śākhā. The word Saṃhitā denotes a systematically arranged collection of Vedic mantras.

The Ṛgveda Saṃhitā consists entirely of metrical hymns (ṛc-s). Each ṛc is a mantra, while a collection of mantras dedicated to a particular Devatā constitutes a sūkta. The Ṛgveda comprises approximately 10,170 ṛc-s arranged into 1,028 sūkta-s and is divided into ten maṇḍala-s or, alternatively, eight aṣṭaka-s.

The Ṛgveda opens with a hymn to Agni and concludes with another hymn addressed to Agni. Within traditional interpretation, Agni is often understood not merely as the physical fire but also as representing the light of knowledge (jñāna) and the radiance of the Ātmā. The concluding hymn of the Ṛgveda is presented as a universal prayer for harmony among humanity, calling for unity of thought, purpose, and mutual goodwill.

The word Yajus derives from the verbal root yaj, meaning "to worship." The same root also gives rise to the word yajña. Whereas the Ṛgveda primarily contains hymns of praise directed toward the Devatā-s, the Yajurveda provides the liturgical procedures governing the performance of sacrifices. Thus, while the Ṛgveda emphasizes verbal praise, the Yajurveda explains the ritual actions through which that worship is expressed.

The Yajurveda exists in two principal forms: the Śukla Yajurveda and the Kṛṣṇa Yajurveda. The Saṃhitā of the Śukla Yajurveda is known as the Vājasaneyī Saṃhitā, traditionally believed to have been revealed to Ṛṣi Yājñavalkya by the solar Devatā.

Traditional accounts narrate that Yājñavalkya originally studied the undivided Yajurveda under Vaiśampāyana. Following a disagreement between teacher and disciple, Yājñavalkya relinquished the knowledge he had received and subsequently sought refuge in the Sun. The solar Devatā then revealed additional Vedic knowledge, which came to constitute the Śukla Yajurveda, while the earlier recension became known as the Kṛṣṇa Yajurveda.

Unlike the Śukla Yajurveda, the Kṛṣṇa Yajurveda intersperses its Brāhmaṇa material among the mantras of the Saṃhitā, rather than preserving the two as distinct textual divisions.

The Ṛgveda is traditionally regarded as the source of hymns addressed to numerous Devatā-s and also contains material relating to ethical life and social institutions. Marriage rituals are based upon hymns connected with the marriage of the daughter of the Sun. The dialogue between Purūravas and Urvaśī later served as the basis for Kālidāsa's Vikramorvaśīyam. Hymns such as those addressed to Uṣas, the goddess of dawn, are also noted for their poetic excellence. Within the traditional understanding, the Ṛgveda forms the basis of the ritual system elaborated in the Yajurveda and the musical traditions embodied in the Sāmaveda.

The distinctive contribution of the Yajurveda lies in its systematic exposition of Karmayoga, the path of ritual action. The Taittirīya Saṃhitā of the Kṛṣṇa Yajurveda contains detailed instructions for sacrifices such as the Darśapūrṇamāsa, Somayāga, Vājapeya, Rājasūya, and Aśvamedha. It also preserves celebrated hymns, including the Śrī Rudram, which occupies a central place in Śaiva worship.

Among contemporary Vedic traditions, followers of the Yajurveda constitute the largest group. The Śukla Yajurveda predominates in much of northern India, whereas the Kṛṣṇa Yajurveda is more widespread in southern India. The Upākarma observed by Yajurvedins consequently became the most widely recognized Vedic observance.

The Yajurveda also occupies a prominent place in the Advaita Vedānta tradition. Of the ten principal Upaniṣad-s, both the Īśāvāsya Upaniṣad and the Bṛhadāraṇyaka Upaniṣad belong to the Yajurveda. Śrī Sureśvarācārya composed his celebrated Vārtika-s on Śaṅkara Bhagavatpāda's commentaries to the Taittirīya Upaniṣad and the Bṛhadāraṇyaka Upaniṣad, both of which belong to the Yajurvedic tradition.

The word Sāman denotes that which brings harmony or tranquillity. The Sāmaveda consists primarily of Ṛgvedic mantras adapted for melodic chanting (Sāmagāna). Whereas Ṛgvedic recitation follows the tonal accents of udātta, anudātta, and svarita, the Sāmaveda renders these mantras according to prescribed musical patterns. Indian classical music is traditionally regarded as having originated from this system of Sāmagāna.

The chanting of the Sāman-s is considered especially effective in invoking the grace of the Devatā-s, particularly during Somayajña-s. Although the mantras themselves originate largely from the Ṛgveda, their musical rendering is regarded as conferring a distinctive spiritual efficacy.

The exalted status of the Sāmaveda is reflected in several traditional texts. In the Bhagavad Gītā, Śrī Kṛṣṇa declares, Vedānāṃ Sāmavedo'smi ("Among the Vedas, I am the Sāmaveda"). Similarly, the Lalitāsahasranāma praises the Goddess as Sāmagāna-priyā, while Śiva is worshipped as Sāmapriya in the Śivāṣṭottaraśatanāma. Tamil devotional literature likewise celebrates the chanting of the Sāman-s.

The Atharvaveda derives its name from the sage Atharvan. It contains mantras relating to protection from misfortune, healing, prosperity, and the removal of obstacles. Its contents comprise both prose and verse. In addition to mantras addressed to familiar Vedic Devatā-s, it includes hymns directed toward powers and beings not prominently represented in the other Vedas. Traditional mantrika practices are often traced to the Atharvaveda.

At the same time, the Atharvaveda contains profound philosophical and devotional material. Among its notable compositions is the Pṛthivī Sūkta, which praises the Earth and all forms of life sustained by her.

Within the sacrificial system, the supervising priest (Brahmā) is traditionally associated with the Atharvaveda. Although Atharvavedic recitation became comparatively rare in later centuries, inscriptions indicate that Atharvavedic schools flourished in parts of South India during the Cōḻa period. Atharvavedic communities also continued in regions such as Gujarat, Saurāṣṭra, Kośala, and Odisha.

Three of the ten principal Upaniṣad-s the Praśna, Muṇḍaka, and Māṇḍūkya Upaniṣad-s belong to the Atharvaveda. The Māṇḍūkya Upaniṣad, in particular, is traditionally regarded as sufficient by itself for those seeking mokṣa.

The Gāyatrī mantra is traditionally regarded as the essence of the first three Vedas. According to one traditional view, students wishing to undertake the study of the Atharvaveda after completing instruction in the other Vedas must undergo a second Upanayana to receive the Atharvavedic Gāyatrī. By contrast, students belonging to the Ṛgveda, Yajurveda, or Sāmaveda traditions may study one another's Vedas without a second initiation.
