Shakala Shakha in the context of "Rig Veda"

The Rigveda or Rig Veda (Sanskrit: ऋग्वेद, IAST: ṛgveda, from ऋच्, "praise" and वेद, "knowledge") is an ancient Indian collection of Vedic Sanskrit hymns (sūktas). It is one of the four sacred canonical Hindu texts (śruti) known as the Vedas. Only one Shakha of the many survive today, namely the Śakalya Shakha. Much of the contents contained in the remaining Shakhas are now lost or are not available in the public forum.

The Rigveda is the oldest known Vedic Sanskrit text. Its early layers are among the oldest extant texts in any Indo-European language. Most scholars believe that the sounds and texts of the Rigveda have been orally transmitted with precision since the 2nd millennium BCE, through methods of memorisation of exceptional complexity, rigour and fidelity, though the dates are not confirmed and remain contentious until concrete evidence surfaces. Philological and linguistic evidence indicates that the bulk of the Rigveda Samhita was composed in the northwestern region of the Indian subcontinent (see Rigvedic rivers), most likely between c. 1500 and 1000 BCE, although a wider approximation of c. 1900–1200 BCE has also been given.

The Aitareya Brahmana (Sanskrit: ऐतरेय ब्राह्मण) is the Brahmana of the Shakala Shakha of the Rigveda, an ancient Indian collection of sacred hymns. This work, according to the tradition, is ascribed to Mahidasa Aitareya.
