Samhita
Samhita (IAST: Saṃhitā) literally means “put together, joined, union”, a “collection”, and “a methodical, rule-based combination of text or verses”. Saṃhitā also refers to the most ancient layer of text in the Vedas, consisting of mantras, hymns, prayers, litanies and benedictions.
Parts of Vedic Samhitas constitute the oldest living part of Hindu tradition.
