This guide to mastering your emotions through traditional yogic, Tantric and Ayurvedic practices is definitely the most fascinating book that I’ve read in a long while. The function and nature of nine primary emotions are explored in detail and are explained in relation to yogic philosophy and Ayurvedic principles. The chapters on each emotion are rich with detailed discussions giving insights, understanding, and most importantly effective tools to cultivate positive emotions and reduce the negative ones. Marchand’s correlation between the effects of the emotional states to western science and biochemistry is captivating and insightful, and clearly shows the relationship between our emotions and our immune system, sense organs, thoughts, diet and lifestyle. This well-written and well-researched book provides both the information and inspiration to utilize our emotions to promote better health, spiritual growth, and enduring happiness.
