Looking into the invisible

'You must not imagine that, just because some people have mediumistic capacities, this necessarily gives them access to every region of the invisible world; on the contrary, they will see only what corresponds to their own level of consciousness, their own thoughts and desires. Each individual receives the degree of clairvoyance that matches his level of evolution; those who are still mired in the lower regions of the astral plane are bound to suffer because they will encounter only the entities of that plane.
If you want to be in communication with heavenly entities, with divine splendour, you must purify yourself, broaden the scope of your consciousness and work for the highest ideal: the brotherhood of all men, the Kingdom of God. When you do this, your emanations become purer, your vibrations subtler, and not only will the spirits of light allow you to reach them, but they themselves will come to you, for they will find nourishment in you.'
