Adhyāya 240: Indriya–Manas–Buddhi–Ātman — The Inner Hierarchy and Restraint (इन्द्रिय-मनस्-बुद्धि-आत्म-क्रमः)
सत्त्वसंसेवनाद धीरो निद्रामुच्छेत्तुमरहति । विद्वानोंने योगके जो काम
sattvasaṃsevanād dhīro nidrām ucchettum arhati | vidvān yoge ye kāma-krodha-lobha-bhayaṃ ca pañcamaṃ svapnam—ime pañca doṣā uktās teṣāṃ pūrṇatayā ucchedaṃ kuryāt | teṣu krodhaṃ śamena (manonigrahena) jayet, kāmaṃ saṅkalpatyāgena parājayet; tathā dhīraḥ sattvaguṇasaṃsevanena nidrāyā ucchedaṃ śaknoti ||
Vyāsa said: By cultivating sattva, a steadfast person becomes fit to cut off sleep. A wise practitioner of yoga should completely uproot the five faults that are taught—desire, anger, greed, fear, and, as the fifth, dreaming. Of these, he should conquer anger through calm self-restraint (control of the mind), and defeat desire by abandoning compulsive resolve and craving-intent. Thus, through sustained reliance on the sattva quality, the resolute person can overcome sleep and remain wakeful in disciplined practice.
व्यास उवाच
A yogic aspirant should uproot five inner faults—desire, anger, greed, fear, and dreaming—and cultivate sattva. Anger is mastered through śama (calm mind-restraint), desire through saṅkalpa-tyāga (renouncing craving-driven resolve), leading to wakeful clarity that overcomes sleep as an obstacle.
In Śānti Parva’s instruction-setting, Vyāsa delivers a didactic teaching on inner discipline. He lists specific psychological impediments to yoga and prescribes concrete counter-practices—mind-restraint and renunciation of desire-intent—framed within the broader ethical program of self-mastery.
