Prahlāda–Indra Saṃvāda: Kartṛtva (Agency) and Svabhāva (Nature) in the Causation of Karma
अथामोघप्रयत्नेन मनो ज्ञाने निवेशयेत् । वाचामोघप्रयासेन मनोज्ञं तत् प्रवर्तते
athāmogha-prayatnena mano jñāne niveśayet | vācāmogha-prayāsena mano-jñaṃ tat pravartate ||
Bhīṣma dit : «Par un effort qui ne se perd pas, qu’on établisse l’esprit dans la connaissance véritable. Et par une parole dont l’élan n’est pas vain, qu’on mette en mouvement ce qui est agréable et salutaire à l’esprit».
भीष्म उवाच
Direct the mind toward jñāna through steady, effective effort, and use speech purposefully so that one’s words promote what is mentally wholesome and conducive to inner steadiness.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and inner governance after the war; here he emphasizes disciplined mental focus on knowledge and restrained, meaningful speech as practical tools for ethical living.
