In the fifth chapter action connected with the body and action connected with the mind are investigated. The text defines and discusses Yoga and Moksha, asserting that self-knowledge (atma-saksatkara) is the means to spiritual liberation. In this chapter, Kanada mentions various natural phenomena such as the falling of objects to ground, rising of fire upwards, the growth of grass upwards, the nature of rainfall and thunderstorms, the flow of liquids, the movement towards a magnet among many others; he then attempts to integrate his observations with his theories, and classifies phenomenon into two: those caused by volition, and those caused by subject-object conjunctions.
