Ālocaka Pitta is situated in the eye, and vision and discrimination of colours are its functions. Sādhaka Pitta is located in the Hṛdaya and it is responsible for intelligence and ego. It is due to this Pitta that all the functions of the mind and body are co-ordinated.

The most important function of Pitta dosha is digestion and metabolism. It is that bio energy present in the body which is responsible for bringing out any type of conversion, transformation or change in the nature of any substance from outside world into the bodily substance. Thus it is the bodily form of Agni element in the Purusha. Apart from digestion, various other functions performed by Pitta dosha are to provide pigmentation to the skin, hair etc, power of vision, discrimination of colors and formation of Rakta from the essence of food. Pitta dosha is the one which is responsible for intelligence and ego and thus,  Pitta dosha also co-ordinates all the functions of the mind and body.
