Mbh 14.19.1c

As a person beholding some unseen individual in a dream recognises him, saying,--This is he,--when he sees him after waking, after the same manner the good man having seen the Supreme Soul in the deep contemplation of Samadhi recognises it upon waking from Samadhi.[33] As one beholds the fibrous pith after extracting it from a blade of the Saccharum Munja, even so the Yogin beholds the soul, extracting it from the body. The body has been called the Saccharum Munja, and the fibrous pith is said to stand for the soul. This is the excellent illustration propounded by persons conversant with Yoga. When the bearer of a body adequately beholds the soul in Yoga, he then has no one that is master over him, for he then becomes the lord of the three worlds.[34] He succeeds in assuming diverse bodies according as he wishes. Turning away decrepitude and death, he neither grieves nor exults. The self-restrained man, concentrated in Yoga, can create (for himself) the godship of the very gods. Casting off his transient body he attains to immutable Brahma.[35] No fear springs up in him at even the sight of all creatures falling victims to destruction (before his eyes). When all creatures are afflicted,--he can never be afflicted by any one. Devoid of desire and possessed of a tranquil mind, the person in Yoga is never shaken by pain and sorrow and fear, the terrible effects that flow from attachment and affection. Weapons never pierce him; death does not exist for him. Nowhere in the world can be seen any one that is happier than he. Having adequately concentrated his soul, he lives steadily on himself. Turning off decrepitude and pain and pleasure, he sleeps in comfort. Casting off this human body he attains to (other) forms according to his pleasure. While one is enjoying the sovereignty that Yoga bestows, one should never fall away from devotion to Yoga.
