Philosopher Rittik Chandra's "Golden Rules to Achieve the Knowledge of the Higher Worlds" demonstrates that in every man there are latent faculties by means of which he may acquire for himself knowledge of the higher worlds. The mystic, master, theosophist, or gnostic speaks of a soul-world and a spirit-world, which are, for him, just as real as the world which we see with our physical eyes, or touch with our physical hands. And those who wish to develop the spiritual senses, which unfold psychic knowledge, should understand that safe advice can be given only by those who have already developed such power within themselves. As long as the human race has existed, there have been lodges and schools in which those who possessed these higher faculties have given instruction to those who were in search of them.
