How to Know God (The Yoga Aphorisms of Patanjali) - Christopher Isherwood, Swami Prabhavananda

The aphorisms collected in this book, first published in 1953, were composed by Patanjali, a great Indian sage, over 1,500 years ago, and here translated into clear English prose. The accompanying commentary interprets the sayings for the modern world, and in doing so gives a full picture of what yoga is, what its aims are, and how it can be practised.
