Shloka 4
Adhyāya 240: Indriya–Manas–Buddhi–Ātman — The Inner Hierarchy and Restraint (इन्द्रिय-मनस्-बुद्धि-आत्म-क्रमः)
योगदोषान् समुच्छिद्य पठच यान् कवयो विदु:
vyāsa uvāca | yogadoṣān samucchidya paṭhaca yān kavayo viduḥ | sattvasaṃsevanād dhīro nidrām ucchettum arhati |
毗耶娑说：“当人彻底斩断那些障碍瑜伽的过失——诸贤者所指明者——坚毅之士便能以修养萨埵（清明与纯净）而驱散昏睡。此教诲的伦理旨趣在于自我净化：修行者须连根拔除内在之敌，如欲、嗔、贪、惧，以及趋向昏眠之习，使澄明与有纪律的觉醒得以支撑瑜伽之道。”

Educational Q&A
Yoga requires removing inner obstacles at their root. By cultivating sattva—purity and clarity—a disciplined person becomes capable of overcoming drowsiness and sustaining wakeful, ethical self-mastery.
In the instructional discourse of the Śānti Parva, Vyāsa gives practical guidance for spiritual discipline, pointing to recognized impediments to yoga and prescribing sattva-cultivation as a means to dispel sleep and maintain steady practice.
