Vedam
The Yajur Veda consists of hymns from the Rig Veda along with other hymns which when recited in the performance of a yajna / havan will enable the Soul or the beneficiaries to understand the universal truths of the Veda in any or all of the three planes of its meanings depending on the individual's stage of spiritual evolution. Though the Yajur Veda is associated with performance of Yajna for worldly gains, it is understood that the individual beneficiaries will ultimately evolve spiritually and subsequently undertake these Yajnas for the spiritual and material benefits of mankind as a whole. The Yajur Veda has two distinct schools of presentation and following as explained below.
Shukla Yajur Veda
This Veda is followed in the Northern parts of India and has mantras in the form of the Veda and Brahmanas (explanatory notes to the mantras) presented in the Satapatha Brahmana. The Shukla Yajur Veda is said to have been taught by the "Sun" to sage Yajnavalkya and hence the name "Shukla" or "White" Yajur Veda.
Krishna Yajur Veda
This is followed in the Southern parts of India and has Veda mantras and Brahmanas intermixed - that is, the Brahmanas follow the mantras as explanatory notes in the Veda text itself. Since Shukla Yajur Veda is known as "White", this Yajur Veda has been denoted as "Krishna" or "Black" Yajur Veda. Both the versions are accepted as authentic and both schools are practised widely.
