Basti is said to be ‘Ardha Chikitsa’ or half the treatment of all the other treatments available in the world. This proves the authority of Vasti treatment over the other treatments.
Vata controls everything –
Vata is said to be the main controlling force of all the activities of the body.
Pitta and Kapha are incapable of producing a disease or disease process unless they are motivated, provoked and mobilized by vitiated Vata.
Similarly the functions of all the tissues and organs, the functions of mind, sense organs, motor organs and all the discharges and movements in the system is carried by the governance of Vata.
The expulsion of wastes from the body is also under its control.
To sum up, Vata is the remote control of all the activities of the body. If this Vata gets vitiatied, the remote control will start controlling the body in an undesired way and cause lot of diseases and deformities.
Thus Vata being the superior dosha, needs a stronger treatment and attention when it is a in a state of vitiation.
Nothing can control a ‘Vata’ which is ‘out of control’ as is done effectively by Vasti.
