Instruction on the Cessation of Craving
मोघान्यगुप्तद्वारस्य सर्वाण्येव भवन्त्युत । कि तस्य तपसा कार्य कि यज्ञेन किमात्मना,जिसके ये द्वार सुरक्षित नहीं हैं, उसके सारे शुभ-कर्म निष्फल होते हैं, ऐसे मनुष्यको तपस्या, यज्ञ तथा आत्मचिन्तनसे क्या लाभ हो सकता है?
moghāny aguptadvārasya sarvāṇy eva bhavanty uta | ki tasya tapasā kāryaṁ ki yajñena kim ātmanā ||
Kapila says: For one whose “doors” are left unguarded, all virtuous efforts become fruitless. What purpose, then, is served by austerity, by sacrifice, or even by inward contemplation, if self-restraint is absent? The ethical point is that discipline of the senses is the foundation that gives spiritual practices their real efficacy.
कपिल उवाच
Spiritual practices like tapas (austerity), yajña (sacrifice), and even inner contemplation bear fruit only when the ‘doors’—commonly understood as the senses and avenues of conduct—are guarded through self-restraint. Without control, good deeds lose their efficacy.
In the Shanti Parva’s instructional dialogue, Kapila is presenting a moral-philosophical critique: he warns that external religious acts and even inward practices are undermined if a person does not discipline the senses and protect the mind from uncontrolled impulses.
