Shloka 13
इन्द्रेण वृत्रवधः, ब्रह्महत्याया अनुगमनम्, तथा च विभाजन-निवासविधानम्
Indra’s defeat of Vṛtra; pursuit by Brahmahatyā; allocation of her abodes
योगदोषान् समुच्छिद्य पठच यान् कवयो विदु:
bhīṣma uvāca | yogadoṣān samucchidya pañca yān kavayo viduḥ—kāmaḥ krodho lobho bhayaṃ nidrā ca | etān mūlataḥ samucchindet, etān parityajya vāk-saṃyamaṃ kṛtvā yogasādhanāni seveta |
毗湿摩说道：“当断除障碍瑜伽之过失——智者所知有五：欲、嗔、贪、惧与睡眠。应从根本拔除；舍弃此等，摄持言语，当勤修瑜伽之诸行。”

Educational Q&A
Yoga requires removing five root obstacles—desire, anger, greed, fear, and sleep/torpor—then practicing disciplined restraint, especially of speech, while cultivating yogic disciplines.
In Shanti Parva, Bhishma instructs Yudhishthira on dharma and inner discipline; here he gives a practical ethical-psychological teaching on what must be uprooted to make yoga effective.
