Adhyāya 240: Indriya–Manas–Buddhi–Ātman — The Inner Hierarchy and Restraint (इन्द्रिय-मनस्-बुद्धि-आत्म-क्रमः)
जैसे मछलीमार जाल काटनेवाली दुष्ट मछलीको पहले पकड़ता है, उसी तरह योगवेत्ता साधक पहले अपने मनको वशगमें करे। उसके बाद कानका, फिर नेत्रका, तदनन्तर जिह्ठा और प्राण आदिका निग्रह करे ।।
tata etāni saṁyamya manasi sthāpayet yatī | tathaivāpohya saṅkalpān mano hātmany dhārayet | sattvasaṁsevanād dhīro nidrām ucchettum arhati ||
毗耶娑说：因此，既已摄持诸根，出家行者当使它们安住于心。又当摒弃一切心造与意向，使心稳固地住于自性（Ātman）。由修习萨埵（sattva，清明与平衡），坚忍之人便堪断除睡眠（昏沉）。

Educational Q&A
Begin yoga by restraining the faculties and placing them under the governance of the mind; then remove saṅkalpas (impulsive intentions and mental fabrications) and steady the mind in the ātman. Cultivating sattva supports alertness and helps uproot nidrā understood as torpor and dullness that obstruct practice.
In Śānti Parva’s instructional discourse, Vyāsa gives practical guidance for an ascetic’s inner discipline: sensory restraint, withdrawal from proliferating intentions, and stabilization of awareness in the Self, emphasizing sattva as the condition for sustained wakeful practice.
