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 ||
ພີສະມະ ກ່າວວ່າ: «ດ້ວຍຄວາມພາກພຽນທີ່ບໍ່ເສຍເປົ່າ ຄວນນໍາໃຈໄປຕັ້ງໄວ້ໃນຄວາມຮູ້ອັນແທ້. ແລະດ້ວຍວາຈາທີ່ຄວາມພະຍາຍາມບໍ່ເປົ່າປະໂຫຍດ ຄວນເຮັດໃຫ້ເກີດການກະທໍາອັນເປັນທີ່ພໍໃຈ ແລະເປັນປະໂຫຍດແກ່ໃຈ».
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.
