महाभारत - शान्ति - द्विविधो व्याधिः

द्विविधो जायते व्याधिः शारीरो मानसस्तथा ।
परस्परं तयोर्जन्म निर्द्वंद्वं नोपलभ्यते ॥

- महाभारत, शान्ति

dvividho jAyate vyAdhiH shArIro mAnasaH tathA ।
parasparaM tayoH janma nirdvandvam na upalabhyate ॥

- mahAbhArata, shAnti

There are two kinds of origins for disease – one is from he body and the other is mental. They are interdependent one each other. Without one, the other does not exist. All diseases are part physical and part mental. Solve one and the other gets solved by itself.
