Explanation:

Vaisheshika is one of the six systems (darshans) of Indian philosophy, significant for its naturalism, a feature that is not characteristic of most Indian thought. The Sanskrit philosopher Kanada Kashyapa (2nd–3rd century CE) expounded its theories and is credited with founding the school.

Mimamsa is one of the six systems (darshans) of Indian philosophy. Mimamsa, probably the earliest of the six, is fundamental to Vedanta, another of the six systems, and has deeply influenced the formulation of Hindu law. The earliest work of the system is the Mimamsa-sutra of Jaimini (c. 4th-century BCE). A major commentary was written by Shabarasvamin (1st century BCE), who was followed by a long line of interpreters and teachers, most notably Kumarila and Prabhakara (7th–8th century CE).

Like the other systems, Nyaya is both philosophical and religious. Its ultimate concern is to bring an end to human suffering, which results from ignorance of reality. Liberation is brought about through right knowledge. Nyaya is thus concerned with the means of right knowledge. In its metaphysics, Nyaya is
allied to the Vaisheshika system, and the two schools were often combined from about the 10th century. Its principal text is the Nyaya-sutras, ascribed to Gautama (c. 2nd century BCE).
