And so with worlds yet higher, knowledge of them is possible, because the Knower is yourself and is God, and you can create your instruments of knowledge according to your wisdom and your will.
Hence Theosophy includes the whole of this vast scheme or field of knowledge; and the whole of it is yours, yours to possess at your will.

Hence Theosophy should be to you a proclamation of your own Divinity, with everything that flows therefrom; and all the knowledge that may be gathered, all the investigations that may be made, they are all part of this great scheme.

And the reason why all the religions of the world teach the same, when you come to disentangle the essence of their teaching from the shape in which they put it, the reason that they all teach the same is that they are all giving you fragments of knowledge of the other worlds, and these worlds are all more real than the world in which you are; and they all teach the same fundamental truths, the same fundamental moral principles, the same religious doctrines, and use the same methods in order that men may come into touch with the other worlds.

The sacraments do not belong to Christianity alone, as sometimes Christians think; every religion has its sacraments, some more numerous than others, but all have some.

For what is a sacrament?
It is the earthly, the physical representative of a real correspondence in nature; as the catechism of the Church of England phrases it: "An outward and visible sign of an inward and spiritual grace." It is a true definition.
