The Yoga Sutras of Patanjali, a foundational Yoga text, forms part of
the corpus of Sutra literature dating back to India's Mauryan period.
The purpose of this text is to reveal the practical means for the birth
of the spiritual being from the psychical body and to indicate the glory
and power of this rebirth. In this text, writer, journalist and
theosophist, Charles Johnston sets forth Patanjali's instructions in an
understandable manner, so as to make his learnings accessible to all.
