By them (the dosas) are produced the viamăgui, the Ukagni and the maridgni respectively; while samagni is produced by their equillibrium.
Notes .._ Agni, literally fire, refers to the fire-like activity in the alimentary canal, responsible or digestion of food. This activity is influenced by the condition of the doas. When all the three doas are in equilibrium, the digestion of food will be perfect in all respects and that is samdgni-normal digestion; but when the doas get aggravated (increased) they bring about their own characteristic changes in the digestive activity also. When Văta is aggravated, the digestion becomes irregular, erratic different from time to time and accompanied with flatulance etc., such a digestive activity, is viamJgni. When Pitta is aggravated the digestive activity is very intense, even large quatities of food get digested very quickly and there is burning sensation, thirst, etc. during digestion; such a condition is Tikgidgni. When Kapha is aggravated the digestive activity is very dull, poor, inadequate, even small quantities of food get digested after a long time and there is heavyness of the abdomen, lassitude, etc. during digestion, such a condition is MandJgni. All these three types are abnormal and give rise to many diseases of the causative doas.
