This is an excellent summary of ten original yoga systems, in which the Author, Ernest Wood, who speaks from more than forty years of experience in Eastern Philosophy, tells us in a very well written and easy to understand language about the teachings and philosophy of these major yoga systems. At the same time, he has also endeavored to preserve the perfect authenticity and clearness of the original teachings of these ten different well-known Oriental schools of yoga teaching and practice. The ten yoga systems are: Raja Yoga, Gita-Yoga, Gnyana-Yoga, Hatha and Laya Yogas, Bhakti and Mantra Yogas, Buddhist Yoga, The Chinese Yoga or Zen, and finally the Sufi Yogas, which includes discussions on Maulana Rumi, Omar Khayyam and other well-known Sufi poets and mystics.
