After reading many, many books on yoga and taking several yoga classes, I was delighted to find this small book on yoga. Though it was written many decades ago, it is very relevant to modern readers. Wood's main strength is that he is able to take the Eastern ideals of yoga practice and express them in a meaningful way to Western readers. He gives equal attention to the eight limbs of yoga, unlike many modern books which tend to focus too much on asanas and perhaps pranayama, with no consideration for the other, equally important aspects of yoga, like pratyahara, dharana, dhyana, and samadhi. A very important book for anyone who is interested in yoga as a spiritual path, and not just a physical exercise routine.
