Shatpatha Brahmana has 100 chapters. This volume contains a comprehensive explanation of Yajurveda. Yajurveda, in conventional terms, is one of the four Vedas. In terms of tatva or essence, it is yajjurveda. There are two words in it--yath and ju. These refer to prana (life-force), vayu (air), gathi (movement) and vak (speech). Shastriji's elucidation of Shatpath Brahmana in Hindi offers insight into various aspects of Yajurveda.
