Ancient and indigenous peoples considered their knowledge of plant medicines to have come from the plants themselves. This heart-centered mode of perception can be exceptionally accurate and detailed in its information gathering if the heart's perceptive abilities are opened. The author explores this mode of perception through the work of numerous healers and researchers such as Luther Burbank, Henry David Thoreau, Masanobu Fukuoka, and Goethe, portraying the commonalities among these individuals in their approach to learning from the plant world. As Buhner outlines the specific steps involved in this method of learning, readers will gain the tools necessary to gather information directly from the heart of nature, to directly learn the medicinal uses of plants, to engage in diagnosis of disease, and to understand the implications of this deep connection.
