Part one, ?A Way of Self-Knowledge, ? contains eight meditations that take the reader on a journey through human experience. Beginning with ordinary experience, Steiner offers ways to imagine and understand the physical body, the elemental (or etheric) body, the elemental world, the Guardian of the Threshold, the astral body, the I-body (or thought body), the nature of experience in suprasensory worlds, and ways of perceiving previous earthly lives. Part two, ?The Threshold of the Spiritual World, ? contains sixteen short chapters in which Steiner provides aphoristic thoughts on trusting one's thinking? cognition of the spiritual world? karma and reincarnation? the astral body and luciferic beings? how to recognize suprasensory consciousness; the true nature of love; and more.
