Adhyāya 240: Indriya–Manas–Buddhi–Ātman — The Inner Hierarchy and Restraint (इन्द्रिय-मनस्-बुद्धि-आत्म-क्रमः)
सत्त्वसंसेवनाद धीरो निद्रामुच्छेत्तुमरहति । विद्वानोंने योगके जो काम, क्रोध, लोभ, भय और पाँचवाँ स्वप्र--ये पाँच दोष बताये हैं उनका पूर्णतया उच्छेद करे। इनमेंसे क्रोधको शम (मनोनिग्रह) के द्वारा जीते, कामको संकल्पके त्यागद्वारा पराजित करे तथा धीर पुरुष सत्वगुणका सेवन करनेसे निद्राका उच्छेद कर सकता है
sattvasaṁsevanād dhīro nidrām ucchettum arhati | vidvān yoge ye kāma-krodha-lobha-bhayaṁ ca pañcamaṁ svapnam—ime pañca doṣā uktās teṣāṁ pūrṇatayā ucchedaṁ kuryāt | eteṣu krodhaṁ śamena (manonigrahena) jayet, kāmaṁ saṅkalpa-tyāgena parājayet, tathā dhīraḥ sattvaguṇa-sevanena nidrāyā ucchedaṁ kartum śaknoti ||
Vyāsa said: By cultivating sattva, a steadfast person becomes fit to cut off sleep. A learned practitioner should completely uproot the five faults taught in yoga—desire, anger, greed, fear, and, as the fifth, dreaming. Among these, he should conquer anger through śama (the restraint of the mind), overcome desire by abandoning compulsive resolve and craving-intention, and by sustained reliance on the sattva-quality the resolute person can bring sleep to an end. The teaching frames self-mastery as the ethical foundation of yogic life: inner discipline, not external force, is the means to freedom from the mind’s disturbances.
