Mahabharata — Shanti Parva, Shloka 10
Prahlāda–Indra Saṃvāda: Kartṛtva (Agency) and Svabhāva (Nature) in the Causation of Karma
इसलिये बुद्धिके द्वारा मनको समाहित करके समस्त प्राणियोंमें स्थित परमात्मामें लगावे। किसीका अहित न सोचे, असम्भव वस्तुकी कामना न करे, मिथ्या पदार्थोंकी चिन्ता न करे और सफल प्रयत्न करके मनको ज्ञानके साधनमें लगा दे। वेदान्त-वाक्योंके श्रवण तथा सुदृढ़ प्रयत्नसे उत्तम ज्ञानकी प्राप्ति होती है ।।
tasmād buddhyā manaḥ samādhāya sarvabhūteṣu sthitaṃ paramātmānaṃ niveśayet | na kasyacid ahitaṃ cintayet, aśakyaṃ vastu na kāṅkṣet, mṛṣāpadārthān na cintayet, saphalaprayatnena ca manaḥ jñānasādhane yojayet | vedāntavākyānāṃ śravaṇena dṛḍhaprayatnena ca uttamajñānaprāptir bhavati || vivakṣatā ca sadvākyaṃ dharmasūkṣmam avekṣatā | satyāṃ vācam ahiṃsrāṃ ca vaded anapavādinīm | yasyāṃ śāṭhyaṃ kāṭhinyaṃ krauryam paiśunyaṃ ca sarvathā nāsti, tādṛśīṃ vācam api svalpamātrāṃ susthiracittena vaktavyām ||
毗湿摩说道：“因此，当以辨慧使心安定，并令其系念于遍住一切众生之至上我（Paramātman）。莫起害人之念；莫求不可能之事；莫为虚妄之境忧思；当以有目的的精进，使心系于求知之道。由聆听吠檀多之言教，并以坚固的努力，得至上之智。又，欲善言者，能观法（dharma）之微细者，当说真实之语，而不含暴害，不涉诽谤。言语应远离欺诳、粗厉、残酷与搬弄是非；即便如此无过之言，也当节制分寸，以安定之心而说。”

Educational Q&A
Discipline the mind through discernment and orient it toward the indwelling Supreme Self; pursue knowledge through Vedantic listening and steady effort; and practice dharmic speech—truthful yet non-harming and free from slander, deceit, harshness, cruelty, and gossip, spoken sparingly with a composed mind.
In the Shanti Parva’s post-war instruction, Bhishma continues advising Yudhishthira on subtle dharma: inner restraint (mind fixed on the Self) and outer conduct (ethical speech) as practical disciplines for attaining higher knowledge and sustaining social harmony.
