Yuddha-yajña-vyākhyāna (The Battle as Sacrifice): Ambarīṣa–Indra Saṃvāda
एतत् तपश्न पुण्यं च धर्मश्वैव सनातन:
etat tapaś ca puṇyaṃ ca dharmaś caiva sanātanaḥ
یہی ریاضت ہے، یہی ثواب ہے، اور یہی سناتن دھرم ہے۔
अम्बरीष उवाच
Ambarīṣa equates the practice under discussion with three inseparable ideals: tapas (disciplined self-restraint), puṇya (moral-spiritual merit), and sanātana-dharma (the timeless ethical order). The verse stresses that true righteousness is not merely a rule but a perennial principle embodied through inner discipline.
In the Śānti Parva’s didactic setting, Ambarīṣa is speaking as a teacher-figure, concluding or affirming a point by declaring that what has just been described constitutes genuine austerity, genuine merit, and the eternal form of Dharma.
