Thus every man in his heaven-life has around him all the friends for whose company he wishes, and they are for him always at their best, because he himself makes for them the thought-form through which they manifest to him. In our limited physical world we are so accustomed to thinking of our friend as only the limited manifestation which we know in the physical world, that it is at first difficult for us to realize the grandeur of the conception; when we can realize it, we shall see how much nearer we are in truth to our friends in the heaven-life than we ever were on earth. The same is true in the case of devotion. The man in the heaven-world is two great stages nearer to the object of his devotion than he was during physical life, and so his experiences are of a far more transcendent character. In this mental world, as in the astral, there are seven subdivisions. The first, second and third are the habitat of the ego in his causal body, so the mental body contains matter of the remaining four only, and it is in those sections that his heaven-life is passed. Man does not, however, pass from one to the other of these, as is the case in the astral world, for there is nothing in this life corresponding to the rearrangement. Rather is the man drawn to the level which best corresponds to the degree of his development, and on that level he spends the whole of his life in the mental body. Each man makes his own conditions, so that the number of varieties is infinite. Speaking broadly, we may say that the dominant characteristic observed in the lowest portion is unselfish family affection. Unselfish it must be, or it would find no place here; all selfish tinges, if there were any, worked out their results in the astral world. The dominant characteristic of the sixth level may be said to be anthropomorphical religious devotion; while that of the fifth section is devotion expressing itself in active work of some sort. All these--the fifth, sixth and seventh subdivisions--are concerned with the working out of devotion to personalities (either to one's family and friends or to a personal deity) rather than the wider devotion to humanity for its own sake, which finds its expression in the next section. The activities of this fourth stage are varied. They can best be arranged in four main divisions: unselfish pursuit of spiritual knowledge; high philosophy or scientific thought; literary or artistic ability exercised for unselfish purposes; and service for the sake of service.
