Thank you WIFW and Kyle Pozorski!
Thank you BAD YOGI MAGAZINE for publishing #YogaInspirationals 76.
One reference for this article is Science of Breath: A Complete Manual of the Oriental Breathing Philosophy of Physical, Mental, Psychic and Spiritual Development (1905). Yoga Publications Society. The book is out of print now, but I borrowed a copy last summer from Laurel Gyland Kieffer. It has provided new insight on breath work in yoga. Some of this will be included in the “Yoga Temple Breath Workshops” I’ll be conducting this summer in Wisconsin and Michigan.
