"The first book of Patanjali's Yoga Sutras is called the Book of Spiritual Consciousness. The second book, which we now begin, is the Book of the Means of Soul Growth. And we must remember that soul growth here means the growth of the realization of the spiritual man, or, to put the matter more briefly, the growth of the spiritual man, and the disentangling of the spiritual man from the wrappings, the veils, the disguises laid upon him by the mind and the psychical nature, wherein he is enmeshed, like a bird caught in a net."
