Yagnavalkya was the founder of Shukla Yajur Ved who was given the knowledge
of Yajurved by Lord Surya. Shukla Yajurved originally had 15 Sakhas
out of which only two sakhas or branches called Madyandina and Kanva
exist at present. Madyandina sakha is more prevalent in North India
where as Kanva Sakha is found mostly in South India. Details of all
the 15 Shakhas can be found in the book Charana Vuyha Tantram.
In both the Madyandina and Kanva sakhas the Brahman is known as Shathpath
Brahman. Shathpath literally means hundred paths. Satha does not exactly
mean 100 it can be even greater then 100 or then that. The Shatapatha
Brahmins describe the Vedic ritual according to the Shukla Yajurved.
