Proper action of a procedure (samyag yoga)

Smoke that properly calms a strong disease is called yoga or samyag yoga; ayoga is use that makes the disease increase, and atiyoga is use of suitable drugs in too large a measure; these three are to be considered in every medicinal procedure.

When head-purging acts properly (samyag yoga), the ears, throat, lips, eyes, mouth, palate and nose are well cleansed together with the strong kapha; physicians who know proper and excessive action are to aim at the proper one.

The signs of proper, deficient (hinayoga) and excessive action given for smoking are to be understood for purgative preparations and for nasya as well.
