A concise, practical guide to the traditional yogic concept of prāṇa—the profound life force that extends beyond the breath to unite our Physical, mental, and spiritual existence. The first volume in the Yoga Masters Series, a landmark collection translating the timeless wisdom of traditional yoga for the modern practitioner. This concise, practical guide to praṇa—the Yogic concept of breath and life force—offers a clear understanding of the ancient wisdom through traditional teachings, modern insights, and practical applications. The significance of breath and the transformative power of breathing practices have been recognized by both ancient Yogis and modern science. Yet, for yogis, prana has traditionally encompassed far more than breath—it’s a profound life force that connects the physical, mental, cosmic, and spiritual dimensions of existence. This book delves into that expansive vision of praṇa, restoring its depth and relevance for the modern practitioner, and presenting an understanding of praṇa as breath and beyond. Yoga educator Prasad Rangnekar draws on the timeless wisdom of the Vedas, Upanishads, Tantra, and Ayurveda, bridging ancient Yogic traditions with modern science. He offers insights and practices on how the principles of prāṇa and practices of prāṇāyāma can be applied not only for respiratory health but also for physical vitality, emotional regulation, mental clarity, meditation, and self-realization.
