SamhitaSaṃhitā literally means "put together, joined, union", a "collection", and "a methodically, 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. Saṃhita is a Sanskrit word from the prefix sam (सम्), 'together', and hita (हित), the past participle of the verbal root dhā (धा) 'put'.
YajurvedaThe Yajurveda (यजुर्वेद, , from meaning "worship", and veda meaning "knowledge") is the Veda primarily of prose mantras for worship rituals. An ancient Vedic Sanskrit text, it is a compilation of ritual-offering formulas that were said by a priest while an individual performed ritual actions such as those before the yajna fire. Yajurveda is one of the four Vedas, and one of the scriptures of Hinduism. The exact century of Yajurveda's composition is unknown, and estimated by Witzel to be between 1200 and 800 BCE, contemporaneous with Samaveda and Atharvaveda.
MantraA mantra (Pali: manta) or mantram (Devanagari: मन्त्रम्) is a sacred utterance, a numinous sound, a syllable, word or phonemes, or group of words in Sanskrit, Pali and other languages believed by practitioners to have religious, magical or spiritual powers. Some mantras have a syntactic structure and literal meaning, while others do not. The earliest mantras were composed in Vedic Sanskrit in India. At its simplest, the word ॐ (Aum, Om) serves as a mantra, it is believed to be the first sound which was originated on earth.
AranyakaThe Aranyakas (ɑːˈrʌnjəkəz; आरण्यक; IAST: ) are a part of the ancient Indian Vedas concerned with the meaning of ritual sacrifice. They typically represent the later sections of the Vedas, and are one of many layers of Vedic texts. The other parts of the Vedas are the Samhitas (benedictions, hymns), Brahmanas (commentary), and the Upanishads (spirituality and abstract philosophy). Aranyakas describe and discuss rituals from various perspectives; some include philosophical speculations.
