Educational Q&A
The body is a temporary aggregation of the five great elements (space, air, fire, water, earth). Their coming together and separating happens according to svabhāva (inherent nature), encouraging detachment and reducing grief or blame regarding birth, change, and death.
In the Shanti Parva, Bhishma instructs Yudhishthira on dharma and wisdom after the war. Here he explains a philosophical point about the elemental constitution of living bodies and the natural process of their formation and dissolution.
