Published in 1895, this special, early treatise on Hatha yoga, is ideal for the yoga practitioner or anyone interested in the history and mythology of the practice. Divided into seven Lessons or Chapters, the book teaches Yoga under seven heads or Sādhanas. The first gives directions for the purification of the Body (inside and out). The second relates to Postures, third to Mudrās, the fourth to Pratyāhāra, the fifth to Prāṇāyāma, the sixth to Dhyāna, and the seventh to Samādhi. These are taught successively—a chapter being devoted to each. We are republishing this vintage work in a modern and affordable edition, complete with a newly written introduction.
