In this classic work of clairvoyant investigation, Charles Leadbeater reveals those hidden aspects of the spiritual world that, once understood, imbue life with greater wisdom, happiness, and progression. While normally glimpsed by only those with psychic powers, the ability exists for all to become a seer or mystic who can then see the “unseen.” All of this is NOT a confirmation that Mr. Leadbeater is always correct (no one is) in his discussion of spiritual phenomena but rather, that this writing will open minds to more fully explore for themselves as to what the heavens, astral planes and hells in truth are.
