Secret Teachings of Plants: the Intelligence of the Heart
 
From prolific herbalism author Stephen Harrod Buhner, The Secret Teachings of Plants explores the difference between brain-based linear cognition and heart-based holistic cognition. While we typically don't think of the heart as an organ of perception, Indigenous cultures from around the world, as well as certain Western thinkers, have long held that the heart can act as a powerful tool for understanding the world.
 
Buhner ties all of these threads together in this remarkable book, weaving discussion of agricultural science together.
