46. As the solar disc which is situated in the heaven above, appears also in the waters below in full blaze; so the soul is situated both in the inside and outside, in the form of the world, (or with the form of imprest ideas in it).
47. Therefore knowing that it is the intellectual soul, that sees the internal dream and the external world in itself; whoso abstains from craving anything is surely blest (because he has every thing in himself. Every soul or mind being full of the thoughts and sights of all things in itself, can be no more in want of anything).
48. The soul is both inseverable and uninflammable (i.e. it can neither be cut asunder nor burnt away); and whoso says otherwise, he must be betrayed by the delusion of duality, as a boy is decoyed by the deceitful yaksha (hocus-pocus).
49. He who sees his inward soul, to view the world internally in itself, is said to be dreaming in himself; and whoso finds his soul looking outwardly on the external world, is known to be waking.
50. Thinking so for regarding the dreaming and waking states, I was inquisitive to know the state of sound sleep, and went on making my inquiries therein.
51. But I thought of what good is the sight of the visible to me? Better remain quiet in myself, because it is the thoughtless oblivion, and consciousness of self, <that> is true insouciance or the stupor or susupti—somnum or hypnotism.
52. As the hair and nails of the body, are never thought of, though they are well known to belong to and to be attached to it; so the mind is quite unconscious of all material and immaterial objects in nature, in its state of sound sleep when it rests in its self-consciousness alone.
53. Tired with the rambles and sights of my waking and dreaming states, I sought my quiet rest in the state of my thoughtless self-consciousness; and this being the sole aim and end of sound sleep, there is no other meaning of the susupti hypnotism.
54. It is possible even in the waking state, to have this sound sleep of susupta hypnotism; by our determination of thinking of naught, save that of sitting quiet in one and same state (of abstractedness).
55. The state of abstraction being arrived at, is termed susupti—sound sleep; but when the sleep is light (Vikshepa), it is called swapnam—somnum or dream.
