In the visible world, all thinking about health and the diseases is done only in terms of the body. Ayurveda recognizes three types of diseases resulting from the three humours of the body: vata (wind) pitta (bile) and shleshma (kaf, cough [phlegm]). Some acharyas of Ayurveda have also analysed diseases on the basis of karma. According to them, the roots of diseases also lie in meritorious and sinful deeds. Tajjo Rogah Karma-yogah. The diseases resulting from merit and sin is the disease resulting from karma. These diseases result not only from vata, pitta and shleshma but also result from karmas. The diseases resulting from the karmas have nothing to do with vata, pitta and shleshma. They are related to the karmas during the previous birth, with meritorious and sinful deeds.
Bhagvan Mahavira has thoroughly explained the doctrine of karma and has provided information about the various results of the karmas. In the Jain philosophy, there is a chapter called "Karmapravada" in the preceding fourteen treatises; the detailed description of the karma and its consequences is available. Today that great treatise is not available, but the sutra relating to karma is available. If we study it carefully, the sutra relating to the disease, health and the karma can be easily understood. Its study opens new dimensions.
