The Astral Plane

The 1899 treatise that set the terms everyone still uses. Leadbeater separates clairvoyance in space from clairvoyance in time, explains what each one actually shows you, and closes with the methods of development he taught his own students.

C. W. Leadbeater

Twenty eight lessons covering the whole family of psychic faculties: clairvoyance in space and time, clairaudience, psychometry, crystal gazing, second sight and astral travel. The widest single course on the subject, with exercises for each faculty.

Swami Panchadasi

A modern hands on manual built around exercises rather than theory. Covers the alpha state, psychic cleansing, reading auras and chakras, and a symbol dictionary for interpreting what you see.

Grumbine taught clairvoyance by correspondence for twenty years, and this is the course he built from it. Lessons on the definition and law of clear seeing, followed by a full treatise on divination and crystal reading.

J. C. F. Grumbine

The companion faculty to clear seeing, treated on its own terms for once. Grumbine works through sound vibration, the silence, dependent and independent voices, and gives practical methods for clairaudient development.
