For serious students of yoga who have an established pranayama practice, this book is a follow-up to Rosen's previous book, The Yoga of Breath. Here he picks up where he left off, offering a selection of traditional yogic techniques for those who wish to deepen their practice of pranayama and their understanding of the ancient wisdom of yoga. Rosen skillfully puts forward an array of awareness disciplines, breathing practices, mudras, and seals, interspersed with anecdotes and quotes from ancient texts.A free audio program available online offers a variety of guided practices so that listeners can create their own pranayama series, with guidance from the author in the appendix.
