The activity of Rāja brings about the awakening from this state by causing the unfoldment of the infolded Ego, mind and senses which resume their operations with external and internal objects as before. The difference between death and sleep lies here. After sleep we resume the functions of our senses, but death is caused by the confusion of our mind, on account of the senses not being able to resume their functions, owing to the disorder of the physical counterparts of the sense-organs through disease. Disease belongs to the physical body, and the senses with the mind and Ego belong to the astral body which we are. The pains we feel are caused by our identifying ourselves with our physical encasement. If we keep the fact constantly alive in our mind that our physical body is the earthly home of our soul, which is the centre of our astral self, we will not only not feel physical pain but prevent or do away with such pain even in the physical body. To know ourselves as nothing but our physical body is the densest, narrowest and the most mischievous ignorance. We often find proofs of this separateness of the physical and mental bodies from acts which present themselves in our daily life; we fail to cognize the experiences of our body or even of our senses when our mind absent from them and absorbed in some other direction. It is the mind that feels pain pleasure, not the body, neither the senses. The physician, through the action of drugs, causes the attribute of Tama to assert itself and cover the mind's perception with its dark veil, so that the patient may not feel the pain of a serious operation on the body, while we feel no pleasure in eating or drinking if our mind is away from them. The Yogi who has, by practice, developed unbroken consciousness of the separatness of the mental and physical body not only enjoys, when the consciousness is absolute, immunity from physical diseases and mishaps, but also does not feel the throes of death when he leaves his worn-out or diseased physical tenement. But the generality of mortals who cannot think of themselves as anything else but their physical bodies, owing to ignorance, suffer from all physical diseases. When these physical diseases put the physical counterparts of sense-organs into disorder, it confuses the mind when it finds that its channels of outward communication, the senses, can no longer work through them. In that confusion it loses its balance and is strongly swayed by the desire to again see and hear and feel and taste, etc.
