Mbh 12.219.3d

Wrong judgment, stupefaction, heedlessness, dreams, and sleepiness, however caused, belong to the attribute of Darkness. Whatever state of consciousness exists, with respect to either the body or the mind, united with joy or satisfaction, should be regarded as due to the quality of Goodness. Whatever state of consciousness exists united with any feeling of discontent or cheerlessness should be regarded as occasioned by an accession of the attribute of Passion into the mind. Whatever state, as regards either the body or the mind, exists with error or heedlessness, should be known as indicative of Darkness which is incomprehensible and inexplicable. The organ of hearing rests on space; it is space itself (under limitations); (Sound has that organ for its refuge). (Sound, therefore, is a modification of space). In perceiving sound, one may not immediately acquire a knowledge of the organ of hearing and of space. But when sound is perceived, the organ of hearing and space do not long remain unknown. (By destroying the ear, sound and space, may be destroyed; and, lastly, by destroying the mind all may be destroyed). The same is the case with the skin, the eyes, the tongue, and the nose constituting the fifth. They exist in touch, form, taste, and smell. They constitute the faculty of perception and they are the mind.[819] Each employed in its own particular function, all the five organs of action and five others of knowledge exist together, and upon the union of the ten dwells the mind as the eleventh and upon the mind the understanding as the twelfth. If it be said that these twelve do not exist together, then the consequence that would result would be death in dreamless slumber. But as there is no death in dreamless slumber, it must be conceded that these twelve exist together as regards themselves but separately from the Soul.
