Perception is explained as a function supported by subtle bodily channels: the ‘fiery’ principle (tejas) is said to be conveyed through the body’s conduits to the eyes, enabling grasping/seeing. The verse frames sense-function as grounded in an underlying psycho-physical order rather than mere surface appearance.
In Śānti Parva’s instructional discourse, Bhīṣma is describing how sensory cognition operates. He outlines how channels spreading through the body, following a principal pathway, reach the eyes while bearing the taijasa quality that empowers perception.
