"The Source" by Dr. Tara Swart, a psychiatrist and neuroscientist, is a self-help book that uses a blend of neuroscience, psychology, and spirituality to guide readers on a journey towards personal transformation. The book argues that by understanding and harnessing the power of the brain, readers can create the life they desire through a four-step program that focuses on unlocking their full potential. The program involves setting intentions, embracing abundance, cultivating focused attention, and engaging in deliberate practice. The author weaves personal anecdotes throughout the text, illustrating how these principles have helped her and her clients overcome obstacles and achieve their goals.
