According to the Mimamsa system of philosophy, liberation is possible by means of

The Purva (or Karman) Mimamsa school treats the Vedic ritual (karma) portion as primary and argues that liberation (moksha) is achieved through the correct performance of Vedic rites and the accumulation of ritual merit (puṇya). Classical Mimamsakas like Jaimini systematized rules for Vedic action, giving ritual practice causal efficacy for freeing the self from rebirth; thus Mimamsa is often called Karmamimamsa and defends ritual action as the path to liberation [1]. Scholarly summaries of Purva Mimamsa likewise state that its goal is to justify and continue Vedic rituals, with moksha attained by performing prescribed duties rather than only by jnana or bhakti [2].
