All the endogenous diseases occur invariably due to the vitiation of ''vata, pitta'' and ''kapha''. As a bird cannot infringe upon its own shadow even by flying throughout the day, in the same way all the diseases are produced by disturbances in equilibrium in ''dhatu'' and cannot occur without vitiation of ''vata, pitta'' and ''kapha''. By examining location, sign and symptoms, causes of vitiation of ''vata'', ''pitta'' and ''kapha'' in any condition, the intelligent physician diagnose all diseases.
