Maharshi Jaimini is a student on Vyasa Maharishi. He is believed to have been born (or to have lived) sometime in the 32nd century BC, at the beginning of the period known, in the Hindu calendar, as the Kali Yuga. His sutras include not only the Rudramsa, Shasthamsa and Saptamsa, but also lagnas (like Varnada Lagna) and yogas (such as Shakti Yoga and Raja Yoga). The Mimamsa sutra contains about 3000 sutras discussing duty (dharma). The first twelve chapters are accepted as being the work of Jaimini, but the four further chapters, comprising about 600 aphorisms, called the Sankarsakanda, show stylistic differences from the earlier part. Recently, however, all sixteen chapters have been attributed to Jaimini. The Mimamsa system received its culmination through Jaimini's work.
