Looking into the invisible : intuition, clairvoyance, dreams

`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.'
