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. (Download instructions
available in the book.)
