Bhishma said: O lord of the earth, best of kings—having conquered desire and anger; cold and heat; rain; fear and grief; the restless breath; the sense-objects that appear dear to human beings; hard-to-overcome discontent; fierce craving; the lure of touch; sleep; and stubborn sloth—one becomes free from attachment. Such a great-souled yogin, endowed with a lofty and refined intellect, accomplishes self-study and meditation, and by the power of discernment directly realizes the subtle Self. Yet, O bull of the Bharatas, the wise Brahmanas have judged this path of yoga to be difficult like a fortress; only a rare person traverses it safely and successfully.

Liberation-oriented yoga requires victory over inner enemies (desire, anger, discontent, craving) and bodily/mental pulls (sleep, laziness, attraction to sense-objects), along with endurance of opposites (cold/heat, rain, fear, grief). Through svādhyāya and dhyāna, guided by buddhi (discernment), the yogin gains direct realization of the subtle Self; however, the tradition acknowledges this path is exceptionally difficult and only rarely completed safely.
In the Shanti Parva’s instruction section, Bhishma continues advising Yudhishthira on the disciplines that lead to peace and the highest good. Here he describes the rigorous yogic path—its required conquests and practices—and adds a sober assessment: even learned Brahmanas call it hard to traverse, and only a few succeed.
