'HISTORY OF MODERN YOGA: PATANJALI AND WESTERN ESOTERICISM'

I have never heard of esoteric folklore so I would assume that is the folklore surrounding esotericism. The reason I have reservations about this is because esoteric practices were secretive by nature and therefore wouldn't accumulate folk beliefs and stories. Just to clarify esotericism was or is a term associated with and used to describe philosophies that couldn't be understood by man or a broad term encompassing mysticism, alchemy, astrology, gnosis, occult and ritual magic.

Ingo Cesaro is known for his works in the field of esotericism and spirituality. Some of his notable books include "Tarot Mirror of the Soul" and "Inner Garden: Meditations for the Heart and Soul." His writings often focus on self-improvement, mysticism, and personal growth through spiritual practices.

Austin Osman Spare was an English artist and occultist known for his innovative approach to magical practice. He was the author of several books, including "The Book of Pleasure (Self-Love)" and "The Book of the Zos Kia Cultus". Spare's work blends elements of art, mysticism, and esotericism.
