Note 12 — II.
Reading edition
We call this the sensual plane, merely because it includes that which is perceived by the senses of our physical body. If the senses of the astral form are developed, the astral plane will also be our sensual plane. There can be no knowledge without perception, and no perception without a sense for that purpose. A system of philosophy based merely upon speculation, and without any perception of truth, is no philosophy at all; but consists merely of vagaries, illusions and dreams.
