Yajurveda in the context of "Shri Rudram"

The Vedas (/ˈveɪdəz/ or /ˈviːdəz/; Sanskrit: वेदः, romanized: Vēdaḥ, lit. 'knowledge'), sometimes collectively called the Veda, are a large body of religious texts originating in ancient India. Composed in Vedic Sanskrit, the texts constitute the oldest layer of Sanskrit literature and the oldest scriptures of Hinduism.

There are four Vedas: the Rigveda, the Yajurveda, the Samaveda and the Atharvaveda. Each Veda has four subdivisions – the Samhitas (mantras and benedictions), the Brahmanas (commentaries on and explanation of rituals, ceremonies and sacrifices – Yajñas), the Aranyakas (text on rituals, ceremonies, sacrifices and symbolic-sacrifices), and the Upanishads (texts discussing meditation, philosophy and spiritual knowledge). Some scholars add a fifth category – the Upāsanās (worship). The texts of the Upanishads discuss ideas akin to the heterodox śramana traditions. The Samhitas and Brahmanas describe daily rituals and are generally meant for the Brahmacharya and Gr̥hastha stages of the Chaturashrama system, while the Aranyakas and Upanishads are meant for the Vānaprastha and Sannyasa stages, respectively.

In Hinduism, Yajna or Yagna (Sanskrit: यज्ञ, lit. 'act of devotion, worship, offering in fire', IAST: yajña) also known as Hawan, is a ritual done in front of a sacred fire, often with mantras. Yajna has been a Vedic tradition, described in a layer of Vedic literature called Brahmanas, as well as Yajurveda. The tradition has evolved from offering oblations and libations into sacred fire to symbolic offerings in the presence of sacred fire (Agni).

Yajna rituals-related texts have been called the Karma-kanda (ritual works) portion of the Vedic literature, in contrast to the Jnana-kanda (knowledge) portion found in the Vedic Upanishads. The proper completion of Yajna-like rituals was the focus of Mimansa school of Hindu philosophy. Yajna have continued to play a central role in a Hindu's rites of passage, such as weddings. Modern major Hindu temple ceremonies, Hindu community celebrations, or monastic initiations may also include Vedic Yajna rites, or alternatively be based on Agamic rituals.

The Samaveda (Sanskrit: सामवेद, IAST: Sāmaveda, from सामन्, "song" and वेद, "knowledge"), is the Veda of melodies and chants. It is an ancient Vedic Sanskrit text, and is one of the sacred scriptures in Hinduism. One of the four Vedas, it is a liturgical text which consists of 1,875 verses. All but 75 verses have been taken from the Rigveda. Three recensions of the Samaveda have survived, and variant manuscripts of the Veda have been found in various parts of India.

While its earliest parts are believed to date from as early as the Rigvedic period, the existing samhita text dates from the post-Rigvedic Mantra period of Vedic Sanskrit, between c. 1200 and 1000 BCE or "slightly rather later," roughly contemporary with the Atharvaveda and the Yajurveda. Along with the Samhita layer of text, the Samaveda includes Brahmana texts, and a final layer of the text that covers philosophical speculations (Upanishads). These layers of the compilation date from the post-Rigvedic Mantra period of Vedic Sanskrit, likely around the 6th century BCE.

The Brahmanas (/ˈbrɑːmənəz/; Sanskrit: ब्राह्मणम्, IAST: Brāhmaṇam) are Vedic śruti works attached to the Samhitas (hymns and mantras) of the Rig, Sama, Yajur, and Atharva Vedas. They are a secondary layer or classification of Sanskrit texts embedded within each Veda, which explain and instruct on the performance of Vedic rituals (in which the related Samhitas are recited). In addition to explaining the symbolism and meaning of the Samhitas, Brahmana literature also expounds scientific knowledge of the Vedic Period, including observational astronomy and, particularly in relation to altar construction, geometry. Divergent in nature, some Brahmanas also contain mystical and philosophical material that constitutes Aranyakas and Upanishads.

Each Veda has one or more of its own Brahmanas, and each Brahmana is generally associated with a particular Shakha or Vedic school. Less than twenty Brahmanas are currently extant, as most have been lost or destroyed. Dating of the final codification of the Brahmanas and associated Vedic texts is controversial, as they were likely recorded after several centuries of oral transmission. The oldest Brahmana is dated to about 900 BCE, while the most recent are dated to around 700 BCE.
