Mbh 14.42.1e

Restraining all desires within the soul, destroying his thirst, concentrated in meditation, and becoming the friend of good heart towards all creatures, he succeeds in becoming fit for assimilation with Brahman. Through repression of all the senses which always hanker after their objects, and abandonment of inhabited places, the Adhyatma fire blazes forth in the man of contemplation. As a fire, fed with fuel, becomes bright in consequence of the blazing flames it puts forth, even so, in consequence of the repression of the senses, the great soul puts forth its effulgence. When one with a tranquil soul beholds all entities in one's own heart, then, lighted by one's own effulgence, one attains to that which is subtler than the subtle and which is unrivalled in excellence. It is settled that the body has fire for colour, water for blood and other liquids, wind for sense of touch, earth for the hideous holder of mind (viz., flesh and bones, etc.), space (or ether) for sound; that it is pervaded by disease and sorrow; that it is overwhelmed by five currents; that it is made up of the five elements; that it has nine doors and two deities;[119] that it is full of passion; that it is unfit to be seen (owing to its unholy character); that it is made up of three qualities; that it has three constituent elements, (viz., wind, bile and phlegm); that it is delighted with attachments of every kind, that it is full of delusions.[120] It is difficult of being moved in this mortal world, and it rests on the understanding as its support. That body is, in this world, the wheel of Time that is continually revolving.[121] That (body), indeed, is a terrible and unfathomable ocean and is called delusion. It is this body which stretches forth, contracts, and awakens the (whole) universe with the (very) immortals.[122] By restraining the senses, one casts off lust, wrath, fear, cupidity, enmity, and falsehood, which are eternal and, therefore, exceedingly difficult to cast off.
