Prahlāda–Indra Saṃvāda: Kartṛtva (Agency) and Svabhāva (Nature) in the Causation of Karma
वाड्मनोभ्यां शरीरेण शुचि: स्यथादनहंकृत: । प्रशान्तो ज्ञानवान् भिक्षुर्निरिपेक्षश्वरेत् सुखम्
vāḍmanobhyāṁ śarīreṇa śuciḥ syād anahaṅkṛtaḥ | praśānto jñānavān bhikṣur nirapekṣaś caret sukham ||
भिक्षू वाणी, मन आणि शरीराने शुद्ध असावा; अहंकाररहित, शांतचित्त आणि ज्ञानवान असावा. निःस्पृह व निरपेक्ष राहून भिक्षावृत्तीने निर्वाह करीत सुखाने विचरावा।
भीष्म उवाच
The verse prescribes the ethical discipline of a renunciant: purity in thought, word, and deed; absence of ego; calmness and discernment; non-dependence and non-craving; and a simple livelihood through alms, leading to contented living.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma after the war. Here he outlines the ideal comportment of a bhikṣu—how such a person should live and sustain himself while cultivating inner purity and peace.
