How do you correlate knowledge of the chakras, as a Spiritist doctor trained in a deterministic view, with the Eastern spiritualist paradigm, with its trans-dimensional perspective? Based on his studies of systemic theory and complexity, the author has developed an understanding that reconciles physiology and philosophy, theory and practice, using simple and accessible language - a result that has culminated in this book. The book seeks to clarify the role of the seven main chakras in health and the soul, bringing practical cases that illustrate how reading the body's signals can lead us to the recovery of our essence as integral beings.
