Purva Mimamsa, also known as Karma Mimamsa, is a school of Hindu philosophy that focuses on the proper interpretation and performance of Vedic rituals and dharma. It is one of the six orthodox schools of Hinduism and is attributed to the sage Jaimini.

In Purva Mimamsa, the concept of reincarnation, also known as samsara, is viewed as an integral part of the cycle of life and death. According to this philosophy, every individual soul (jiva) is eternal and goes through a continuous cycle of birth and death, based on their actions and deeds in their previous lives.

Purva Mimamsa believes that the ultimate goal of human life is to attain liberation (moksha) from this cycle of birth and death. This liberation can be achieved by performing Vedic rituals and fulfilling one's dharma (duty) in the most precise and accurate manner. The performance of these rituals is believed to lead to the accumulation of good karma, which in turn leads to a better rebirth in the next life.

The concept of reincarnation in Purva Mimamsa is closely tied to the doctrine of karma. Karma refers to the law of cause and effect, where every action has a corresponding consequence. This means that the actions and deeds of an individual in their current life will determine their future rebirth and experiences.

Purva Mimamsa also believes in the concept of transmigration of the soul. This means that the soul can take on different forms in different lives based on the accumulated karma. For example, a person who has accumulated good karma may be reborn as a human, while someone with negative karma may be reborn as an animal.

The philosophy of Purva Mimamsa also emphasizes the importance of performing rituals and dharma in the present life. It is believed that the performance of Vedic rituals not only leads to good karma but also purifies the soul and helps in the attainment of moksha.

In conclusion, Purva Mimamsa views the concept of reincarnation as an essential aspect of the cycle of life and death. It stresses the importance of performing Vedic rituals and fulfilling one's dharma in order to accumulate good karma and ultimately attain liberation from this cycle.
