In other worlds

To say that the spirit world is created by the human brain is like saying that the atmosphere and the dry land are created by our lungs. Certainly to the tadpole the dry land is an unknown unknown, beyond comprehension and imagination. As he grows older, something changes within him and because of this he becomes able to learn of the world above water, not merely from a distance but firsthand. So to him, the lungs have indeed "created" a new reality. But objectively speaking, he is a newcomer in a world that has long been. It is likewise with the human mind and its ability to travel to worlds beyond the senses. This is the reason we can, for instance, come there and find something new, only to learn later that others found the same millennia ago.
