When man advances in age he shows a return of the same qualities. First the jinn quality; when he has had all the experience of the world and has reached a certain age he becomes most keen to express all that is beautiful. At this age human beings become intelligent, they speak, they teach, they understand things which young people cannot understand; the jinn quality develops. And when he advances further in age, then the angelic quality develops, then innocence comes with its engaging smiles, then all malice and prejudice are gone and a quality of continually giving out begins to manifest. If one does not see these qualities developing in some people this is usually because they are more engrossed in the world, and then the natural development does not show itself.'
