Yamuna's doctrine of Soul
151
jects of consciousness is left in the mind, so that through them the object of memory may be remembered. During deep sleep no objects are perceived, and no impressions are left, and, as a result, we cease to have any memory of those states. The self then remains with its characteristic self-consciousness, but without the consciousness of anything else. The self-conscious self does not leave any impression on the organs of the psychosis, the manas, etc., as they all then cease to act. It is easy to understand that no impression can be made upon the self; for, if it could and if impressions had been continually heaped on the self, then such a self could never manage to get rid of them and could never attain emancipation. Moreover, it is the characteristic of the phenomenon of memory that, when a perception has once been perceived, but is not being perceived continually, it can be remembered now, when those past impressions are revived by association of similar perceptions. But the self-conscious self has always been the same and hence there cannot be any memory of it. The fact that on waking from deep sleep one feels that one has slept happily does not prove that there was actually any consciousness of happiness during deep sleep; it is only a happy organic feeling of the body resulting from sound sleep which is interpreted or rather spoken of as being the enjoyment of happiness during deep sleep. We say, "I am the same as I was yesterday," but it is not the self that is remembered, but the particular time association that forms the content of memory.

Perception of objects is generated in us when consciousness comes in contact with the physical objects in association with this or that sense of perception. It is on that account that, though the self is always possessed of its self-consciousness, yet it is only when the consciousness of the self is in touch with an external object in association with a sense-organ that we get that particular senseperception. This self is not all-pervading, but of an atomic size; when it comes in association with any particular sense, we acquire that particular sense-perception. This explains the fact that no two perceptions can be acquired simultaneously: where there is an appearance of simultaneity, there is only a succession of acquirement so rapid that changes cannot be noticed. Had the soul been allpervading, we should have had the knowledge of all things at once, since the soul was in touch with all things. Thus it is proved that the self has consciousness as its essential characteristic; knowledge
