PHYSIOLOGICAL ASPECT OF AALOCHAK PITTA PERSPECTIVE OF THE MODERN ERA

Ayurvedic science is based on Dosha, Dhatu, and Mala Vijnana. The body's origin and maintenance depend upon the three primary and fundamental units or principles: Doshas Vata, Pitta, and Kapha. The first Aacharya to categorise Pitta Dosha into five categories was Sushruta. Rupa grahana, or the perception of vision, is attributed to the Pitta known as Alochaka Pitta, located in the retina (Drishti). Acharya Bhela has divided this Alochaka Pitta into two categories: intellectually (Buddhi) and visually or optically (Chakshu’s) differentiative. An example of an optically differentiative Pitta creates a differentiation by placing a picture. The visual process, also known as the physiology of vision, is the mechanism by which the outside world is perceived. Specialised cells called photoreceptors start the process that turns light rays into nerve impulses. There are two categories of photoreceptors: Rodes and cones.
