Experiences becoming fine become impressions; impressions revivified become memory. The word memory here includes unconscious co-ordination of past experiences, reduced to impressions, with present conscious action. In each body, the group of impressions acquired in a similar body only becomes the cause of action in that body. The experiences of a dissimilar body are held in abeyance. Each body acts as if it were a descendant of a series of bodies of that species only; thus, consecutiveness of desires is not to be broken.
