But it is not only that the mind adorns itself in a certain form in order to tell you that you are going to have a good or a bad experience, it is the natural outcome of things; it is an action and a reaction; what we take from the outer world is prepared in the mind and it reacts again in another form which gives us a sort of key by which to understand what the next step will be. In that form, it is a warning. There is no need to take it as a warning in a spiritualistic form, and claim that a spirit, or ghost, or angel came to tell you the future.
