Next is Agni Mahaboota after Vayu
Mahabhoota, which has the vision (Roopa) as its sense attribute and warmth
(Ushnatwa) as its main property. This helps in viewing the creation in life.
In living beings Agni Mahabhoota is the major constituent of biological
humor Pitta dosha. Agni provides the energy necessary for all activities in
our body and can be utilized by our cells. As long as this Agni is proper,
all the activities in body are carried out smoothly. Any disturbance in this
Agni causes imbalance in the homeostasis (equilibrium) and disturbs
physiology.
Entire Ayurvedic therapeutics is based on this concept of Agni. The branch
of Ayurved which deals with internal medicine and treatment is called "Kayachikitsa",
where Kaya means Agni and Chikitsa means treatment.
