By the power of dhauti practice, the digestive fire increases. There is no disease nor aging, and the body is nourished.

This verse describes the deeper benefits of dhauti. Jaṭharāgni (the digestive fire) vivardhate (increases/strengthens). A strong agni is the foundation of health according to Āyurveda — it digests not only food but also toxins and emotional experiences.

The promises are extraordinary: naiva rogaḥ (no disease) and na jarā (no aging). Although they may seem hyperbolic, they express the principle that optimal digestion is the root of longevity and resistance to disease.

Dehapuṣṭikṛt means “that which nourishes the body.” Paradoxically, regularly emptying the digestive system allows for more efficient nutrition. Intestinal walls free of residue absorb nutrients better, and the system does not waste energy processing accumulated toxins.
