Explanation:

Mimamsa is a Sanskrit word that means "reflection" or "critical investigation" and thus refers to a tradition of contemplation which reflected on the meanings of certain Vedic texts.This tradition is also known as Purva-Mimamsa because of its focus on the earlier Vedic texts dealing with ritual actions, and similarly as Karma-Mimamsa due to its focus on ritual action (karma). It is one of six Vedic "affirming" (astika) schools of Hinduism. This particular school is known for its philosophical theories on the nature of dharma, based on hermeneutics of the Vedas, especially the Bra?manas and Sa?hitas. The Mimamsa school was foundational and influential for the vedantic schools, which were also known as Uttara-Mima?sa for their focus on the "later" (uttara) portions of the Vedas, the Upani?ads. While both "earlier" and "later" Mimamsa investigate the aim of human action, they do so with different attitudes towards the necessity of ritual praxis.
