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
sattvasaṃsevanād dhīro nidrām ucchettum arhati | vidvān yoge ye kāma-krodha-lobha-bhayaṃ ca pañcamaṃ svapnam—ime pañca doṣā uktās teṣāṃ pūrṇatayā ucchedaṃ kuryāt | eṣu krodhaṃ śamena (manonigrahena) jayet, kāmaṃ saṅkalpatyāgena parājayet, tathā dhīraḥ sattvaguṇasaṃsevanena nidrāyā ucchedaṃ kartum arhati ||
Vyāsa said: By cultivating sattva, a steadfast person becomes fit to cut off sleep. The wise declare that in the discipline of yoga there are five faults—desire, anger, greed, fear, and as the fifth, dreaming; one should eradicate them completely. Among these, anger is to be conquered by calm self-restraint, desire is to be overcome by abandoning compulsive resolve, and the steady-minded, by nourishing sattva, can bring sleep to an end.
व्यास उवाच
Yoga requires removing five obstacles—desire, anger, greed, fear, and dreaming—through specific remedies: anger by śama (mental restraint), desire by giving up binding saṅkalpa (compulsive intention), and dullness/sleep by cultivating sattva.
In the instruction-heavy Shānti Parva, Vyāsa continues a didactic passage on inner discipline, listing common psychological impediments to yogic practice and prescribing practical methods to overcome them.
