But each draws from it and cognizes so much of it as he has by previous effort prepared himself to take. Different individuals bring very different capacities; they tell us in the East that each man brings his own cup, and some of the cups are large and some are small, but small or large every cup is filled to its utmost capacity; the sea of bliss holds far more than enough for all.
A man can look out upon all this glory and beauty only through the windows which he himself has made. Every one of these thought-forms is such a window, through which response may come to him from the forces without. If during his earth-life he has chiefly regarded physical things, then he has made for himself but few windows through which this higher glory can shine in upon him. Yet every man who is above the lowest savage must have had some touch of pure unselfish feeling, even if it were but once in all his life, and that will be a window for him now.
The ordinary man is not capable of any great activity in this mental world; his condition is chiefly receptive, and his vision of anything outside his own shell of thought is of the most limited character. He is surrounded by living forces, mighty angelic inhabitants of this glorious world, and many of their orders are very sensitive to certain aspirations of man and readily respond to them. But a man can take advantage of these only in so far as he has already prepared himself to profit by them, for his thoughts and aspirations are only along certain lines, and he cannot suddenly form new lines. There are many directions which the higher thought may take—some of them personal and some impersonal. Among the latter are art, music and philosophy; and a man whose interest lay along any one of these lines finds both measureless enjoyment and unlimited instruction waiting for him—that is, the amount of enjoyment and instruction is limited only by his power of perception.
We find a large number of people whose only higher thoughts are those connected with affection and devotion. If a man loves another deeply or if he feels strong devotion to a personal deity, he makes a strong mental image of that friend or of the deity, and the object of his feeling is often present in his mind. Inevitably he takes that mental image into the heaven-world with him, because it is to that level of matter that it naturally belongs.
Take first the case of affection. The love which forms and retains such an image is a very powerful force—a force which is strong enough to reach and to act upon the ego of his friend in the higher part of the mental world. It is that ego that is the real man whom he loves—not the physical body which is so partial a representation of him. The ego of the friend, feeling this vibration, at once and eagerly responds to it, and pours himself into the thought-form, which has been made for him; so that the man's friend is truly present with him more vividly than ever before. To this result it makes no difference whatever whether the friend is what we call living or dead; the appeal is made not to the fragment of the friend which is sometimes imprisoned in a physical body, but to the man himself on his own true level; and he always responds. A man who has a hundred friends can simultaneously and fully respond to the affection of every one of them, for no number of representations on a lower level can exhaust the infinity of the ego.
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.
Even to this glorious heaven-life there comes an end, and then the mental body in its turn drops away as the others have done, and the man's life in his causal body begins. Here the man needs no windows, for this is his true home and all his walls have fallen away. The majority of men have as yet but very little consciousness at such a height as this; they rest dreamily unobservant and scarcely awake, but such vision as they have is true, however limited it may be by their lack of development. Still, every time they return, these limitations will be smaller, and they themselves will be greater; so that this truest life will be wider and fuller for them.
As this improvement continues, this causal life grows, longer and longer, assuming an ever larger proportion as compared to the existence at lower levels. And as he grows, the man becomes capable not only of receiving but also of giving. Then indeed is his triumph approaching, for he is learning the lesson of the Christ, learning the crowning glory of sacrifice, the supreme delight of pouring out all his life for the helping of his fellow-men, the devotion of the self to the all, of celestial strength to human service, of all those splendid heavenly forces to the aid of the struggling sons of earth. That is part of the life that lies before us; these are some of the steps which even we who are still so near the bottom of the golden ladder may see rising above us, so that we may report them to those who have not seen as yet, in order that they too may open their eyes to the unimaginable splendour which surrounds them here and now in this dull daily life. This is part of the gospel of Theosophy—the certainty of this sublime future for all. It is certain because it is here already, because to inherit it we have only to fit ourselves for it.
