The ''tridosha'', when vitiated, are considered as the intrinsic cause of the disease, and they either confer a predisposition to or actually cause morbidities.

''Doshas'' are susceptible to imbalance and vitiation and in turn they vitiate other structural and functional elements of the body. They are also known as ''dhatus'' as they support the body in their state of equilibrium, which represents normalcy. The state of equilibrium of ''doshas'' i.e. ''samyata'' or ''arogata'' is a disease free state. On the contrary, a diseased state is due to a deviation from the state of equilibrium(A. Hr. Su. 1/20). The unbalanced ''doshas'' are also called ''malas'' when they start vitiating the body.

Further in this chapter, it becomes very evident that the functions of ''vata dosha'' correspond very much not only to the functions of nervous system but also to functions of any system concerned with regulation, signaling, conduction and control of any information or any system in our body.

''Vata'' is regarded as the carrier of objects to their sense faculties and is the direct cause of skin and tactile sensation, without which no other sense faculty can enjoy their recipients perception (Cha. Su. 11/38).

All the sensory faculties are felt and respond only when they are conducted from the sensory point to the brain and are interpreted there.

''Vata'' is the impeller of the speech. Speech has been considered as the distinctive feature of ''akasha mahabhuta'' but is included under the next ''mahabhuta'' of ''vayu'' ( Cha. Su. 1/28) and hence speech has also been considered due to ''vata dosha''.

Presence of ''vayu'' is essential for the production of sound. Sound waves result from the alternate compression and decompression of air molecules. They originate from a vibrating object, much the same way as water waves travel over the surface of water.

Initially unicellular microorganism called ''beeja'' grows into a full-grown multi-cellular organism by mitotic division of cells, attributed to ''vata dosha'' - ''vayur vibhajati'' means ''vata'' controls formation of various body parts and organs. Therefore deranged functions of ''vata'' can lead to congenital abnormalities.
