300–200 BCE[1]), written by Rishi Jaimini is one of the most important ancient Hindu philosophical texts.
It forms the basis of Mimamsa, the earliest of the six orthodox schools (darshanas) of Indian philosophy.
[3] The major commentaries written on the text, including the Śabara Bhāṣya, were by Kumarila Bhatta and Prabhakara Mishra.
Ramanuja, Bhāskara (Bhedabheda Vedanta), Madhvacharya and Vallabha considered Pūrvamīmāṃsā and Uttaramīmāṃsā (Vedanta) as ekaśastra i.e. one undivided teaching: [citation needed] Jaimini, in his Mimamsa Sutra, presents material activity and its results as the whole of reality (vipanam rtam).
Therefore, they assert that the primary purpose of the Vedas is to engage human beings in rituals for creating good karma, and consequently the mature soul's prime responsibility is to ascertain the exact meaning of the Vedas' sacrificial injunctions and to execute them.
