Healing and occult science

This book examines healing through the lens of occult science, likely combining spiritual, symbolic, and esoteric explanations of health and illness. Its importance lies in the period when occultism often overlapped with alternative medicine and spiritual therapeutics; readers will find theories of subtle forces, mind-body relations, and methods of spiritual or energetic healing.

J. Croiset Van Uchelen appears to be an obscure author or contributor associated with esoteric or occult literature. I cannot confidently identify specific biographical details without further reliable context.
