We may take it as an axiom that any law which appears to limit us contains in itself the principle by which that limitation can be overcome, just as in the case of the flotation of iron.

In this axiom, then, we shall find the clue which will bring us out of the labyrinth.

The same law which places various degrees of limitation upon the souls that have passed into the invisible can be so applied as to set them free.

We have seen that everything turns on the obligation of our subjective part to act within the limits of the suggestion which has been most deeply impressed upon it.

Then why not impress upon it the suggestion that in passing over to the other side it has brought its objective mentality along with it?
If such a suggestion were effectively impressed upon our subjective mind, then by the fundamental law of our nature our subjective mind would act in strict accordance with this suggestion, with the result that the objective mind would no longer be separated from it, and that we should carry with us into the unseen our _whole_ mentality, both subjective and objective, and so be able to exercise our inductive powers of selection and initiative as well there as here.
Why not?
The answer is that we cannot accept any suggestion unless we believe it to be true, and to believe it to be true we must feel that we have a solid foundation for our belief.
