21. He who sees the vacuum as the plenum, and views this all omnium as the null and nullum; and whose mind is even and tranquil, is the man who is called the sleeping silent sage.
22. Again he who views the universe as neither reality nor unreality either, but all an empty vacuum and without a substratum, but full of peace and divine wisdom, is said to be in the best state of his taciturnity.
23. The mind that is unconscious of the effects, of the different states of its prosperity and adversity and of its plenty and wants, is said to rest in its highest state of rest and quiet.
24. That perfect equanimity of the mind and evenness of temper, which is not liable to change or fluctuation; with a clear conscience and unflinching self-consciousness, are the source of an unimpairing reticence.
25. The consciousness that I am nothing, nor is there anything besides; and that the mind and its thoughts, are no other in reality (than fictions of the intellect); is the real source of taciturnity.
26. The knowledge that the ego pervades this universe, which is the representation of the "one that is"; and whose essence is displayed equally in all things, is what is meant by the state of sleepy silence. (i.e. the man that has known this grand truth, remains dumb and mute and has nothing to say).
27. Now as it is the consciousness which constitutes all and everything, how can you conceive your distinction from others, who are actuated by the same power, dwelling alike in all? It is this knowledge which is called the ever lasting sleep, and forms the ground work of every kind of silence.
28. This is the silence of profound sleep, and because it is an endless sleep in the ever wakeful God, this sleep is alike to waking. Know this as the fourth stage of Yoga, or rather a stage above the same.
29. This profound trance is called hypnotism or the fourth state of entranced meditation; and the tranquillity which is above this state, is to be had in one's waking state.
