Varṇa-lakṣaṇa and Ātma-saṃyama (Marks of Social Conduct and Self-Restraint) | वर्णलक्षणम् एवं आत्मसंयमः
समुन्नमग्रतो वस्त्र पश्चाच्छुध्यति कर्मणा । उपवासै: प्रतप्तानां दीर्घ सुखमनन्तकम्
samunnam agrato vastraṁ paścāc chudhyati karmaṇā | upavāsaiḥ prataptānāṁ dīrghaṁ sukham anantakam ||
ଭୀଷ୍ମ କହିଲେ—ଯେପରି ପୂର୍ବରୁ କ୍ଷାର ଆଦିରେ ଭିଜାଇ ରଖାଯାଇଥିବା ବସ୍ତ୍ର ପରେ ଧୋଇବା କ୍ରିୟାରେ ଶୁଦ୍ଧ ହୋଇଯାଏ, ସେପରି ଉପବାସରେ ତପ୍ତ ହୋଇ ଯେମାନେ ତପସ୍ୟା କରନ୍ତି, ସେମାନେ ଦୀର୍ଘକାଳୀନ ଓ ଅନନ୍ତ ମହାସୁଖ ପାଆନ୍ତି।
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.
