Madhyandina Shakha is a shakha (branch) of Shukla Yajurveda. This branch includes Madhyandina Samhita, Madhyandina Shatapatha Brahmana, Ishavasya Upanishad and Brihadaranyaka Upanishad. Recitation of this Shakha is prevalent over most of North India, Maharashtra and among Veda pandits of Gujarat.
Traditions
North Indian Veda Pandits recite it in a different way compared to those from Maharashtra. The former pronounce the syllable ष (ṣa) as ख (kha).
