Part muscle, part engine, part soul, the human heart is the emotional and spiritual compass of the body. Yet, when the heart becomes diseased, modern medicine only diagnoses its symptoms clinically, failing to explore a patient's spiritual life. In Just One Heart, cardiologist and mindfulness teacher Dr Jonathan Fisher offers a radical new perspective on understanding heart health and happiness. He argues that there is a complex interplay between the heart and mind that affects our overall well-being. With this holistic outlook, he bridges the longstanding divide between Eastern spirituality and Western science, heralding a renewed, integrated approach to heart health that encompasses the mind, body, and spirit. In this life-changing book, you will find: seven timeless qualities to protect the heart for holistic health and vitality; practical tools to navigate anxiety and burnout; easy explanations on how the heart functions; daily practices such as heart meditation, mindful journalling and community involvement, among others, that strengthen the heart's resilience. Drawing on inspiring stories of those afflicted by heart disease and conversations with more than fifty experts in mind-body health, this compassionate guide empowers readers to connect with what truly matters - the awakening of the mind-heart connection. It is essential reading for healthcare professionals, their patients and anyone seeking lasting health, peace of mind and happiness.
