|Rig Veda Manuscript|
The four main divisions of the Vedas are as follows:
Samhitas: These were collections of metrical hymns, prayers, and songs usually sung or chanted during the performance of various rites and sacrifices.
Brahmanas: These were prose commentaries and theological discussions on the meaning of the various texts, sacrifices, and ceremonies.
Aranyakas: Also known as the “forest texts”, these were, partly appended to the Aranyakas and partly independent, commentaries and meditations by hermits living in the forest on the significance of the rituals and sacrifices described in the Vedic hymns.
Upanisads: These were also usually either part of the Aranyakas or independent of them, without any absolute dividing point. For instance, The Brihadaranyaka Upanishad is both an Aranyaka and an Upanishad and forms the last part of the Satapatha-Brahmana, a Brahmana of the White Yajur-Veda. The Upanishads are mystical contemplations on the meaning of the world, soul, life, death, and reality.
Rig Veda: The word Rig comes from ṛc and means “praise, verse”. Thus, Rig Veda is the book of Praise-knowledge. The Veda is organized into 10 books, known as Mandalas, each consisting of several hymns or Suktas. The Suktas consist of stanzas called ṛc that can be further analysed into pada (foot) or verses.
Sama Veda: The collection is derived from the word Saman, meaning "melodies"; thereby, Sama Veda is the book of the "knowledge of melodies". It is considered that the hymns in this book were mainly used during the Soma sacrifice and many of the hymns are repeated from the Rig Veda.
Yajur Veda: Yajus means “sacrificial formula”; thus, Yajur Veda gives the “knowledge of sacrificial formulas”. There are two primary versions of this, viz. the Shukla Yajur Veda (White Yajur Veda) and the Krishna Yajur Veda (Black Yajur Veda). While the White Yajur Veda focuses on liturgy, the Black Yajur Veda has more explanatory material about the rituals.
Atharva Veda is the book of the “knowledge of magic formulas” (atharvan). It is a collection of spells, prayers, charms, and hymns with “prayers to protect crops from lightning and drought, charms against venomous serpents, love spells, healing spells,” containing hundreds of verses, some derived from the Rig Veda.
