Mimamsa: According to this philosophy liberation is possible by means of karma Mimamsa is a Sanskrit word that means "reflection" or "critical investigation" It is one of six orthodox (astika) schools of Hinduism. The school is known for its philosophical theories on the nature of dharma, based on hermeneutics of the Vedas The Mīmāṃsā school was foundational and influential for the vedānticschools, which were also known as Uttara-Mīmāṃsā. The differences were that the Mīmāṃsā school developed and emphasized karma-kāṇḍa, or the study of ritual actions, using the four early Vedas, while the Vedānta schools developed and emphasized jñana-kāṇḍa, the study of knowledge and spirituality, using the later parts of Vedas like the Upaniṣads. The school of Mīmāṃsā consists of both atheistic and theistic doctrines, but the school showed little interest in systematic examination of the existence of God. Rather, it held that the soul is an eternal, omnipresent, inherently active spiritual essence, and focused on the epistemology and metaphysics of dharma. The Mīmāṃsā school of Hinduism is a form of realism A key text of the Mīmāṃsā school is the Mīmāṃsā Sūtra of Jaimini Between the Samhitas and Brahmanas, the Mimamsa school places greater emphasis to the Brahmanas - the part of Vedas that is a commentary on Vedic rituals Purva-Mimamsa was just known as the Mimamsa school, and the Uttara-Mimamsa as the Vedantaschool The scholars of Mimamsa school are referred to as the Mimamsakas The core tenets of Pūrva Mīmāṃsā are ritualism (orthopraxy), anti-asceticism and anti-mysticism. The central aim of the school is elucidation of the nature of dharma, understood as a set ritual obligations and prerogatives to be performed properly.
