भीष्म उवाच
Fasting undertaken as disciplined austerity (tapas) purifies the practitioner and yields enduring, even ‘endless,’ well-being; purification is presented as a process—preparation plus sustained effort—like washing a pre-treated cloth.
In the Shanti Parva’s instruction on dharma and right conduct, Bhishma continues advising by using a household analogy (cloth cleaned after being treated) to explain how ascetic practices—especially fasting—lead to inner purification and lasting happiness.
