Vedism is India's oldest stratum of religious activity, for written materials exist. It was one of the significant traditions that shaped Hinduism. There are four types of Vedas- Rig, Yaju, Sama and Atharva. Yajurveda has two categories: Krishna Yajurveda and Shukla Yajurveda. The Krishna Yajurveda contains 7 Khandhas. Khandhas are divided into 44 chapters called Parchas. Tradition has it that Namboothiri was established in 64(traditional) villages—the 32 original settlements, as given in the Keralolpathi. The Vedas comprise a vast corpus of Sanskrit poetry, philosophical ideas, mythology and ritual incantations developed and composed by Aryans over 3,500 years ago. It also discusses the Yaga culture and Tantric traditions. Regarded by Hindu culture (Hindus) as the primary source of knowledge and the sacred foundation of their religion, the Vedas embody one of the world’s oldest surviving cultural traditions. The Vedic heritage embraces a multitude of texts and interpretations collected in four Vedas, commonly referred to as “books of knowledge,” which is unlimited knowledge, even though they have been transmitted orally. The Rig Veda is an anthology of sacred hymns; the Sama Veda features musical arrangements of accolades from the Rig Veda and other sources; the Yajur Veda abounds in prayers and sacrificial formulae used by priests, Yaga mantras; and the Atharva Veda includes incantations and spells. The Vedas also offer insight into the history of Hinduism and the early development of several artistic, scientific and philosophical concepts, such as the concept of zero. Expressed in the Vedic language, which is derived from classical Sanskrit, the verses of the Vedas were traditionally chanted during sacred rituals and recited daily in Vedic communities. The value of this tradition lies not only in the rich content of its oral literature but also in the ingenious techniques employed by the Brahmin priests in preserving the texts intact over thousands of years. To ensure that the sound of each word remains unaltered, practitioners are taught from childhood complex recitation techniques based on tonal accents, a unique manner of pronouncing each letter and specific speech combinations.
