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. Chapter VII REINCARNATION This life of the ego in his own world, which is so glorious and so fully satisfying for the developed man, plays but a very small part in the life of the ordinary person, for in his case the ego has not yet reached a sufficient stage of development to be awake in his causal body. In obedience to the law of Nature he has withdrawn into it, but in doing so he has lost the sensation of vivid life, and his restless desire to feel this once more pushes him in the direction of another descent into matter. This is the scheme of evolution appointed for man at the present stage--that he shall develop by descending into grosser matter, and then ascend to carry back into himself the result of the experiences so obtained. His real life, therefore, covers millions of years, and what we are in the habit of calling a life is only one day of this greater existence. Indeed, it is in reality only a small part of one day; for a life of seventy years in the physical world is often succeeded by a period of twenty times that length spent in higher spheres.
