Note 1 — Chapter VIII · A Tempter.

Yoga (concentration) is the name of the second division of the Sánkhya system of Hindu philosophy. It was first taught by Patanjali. He asserted that the soul was Iswara (God), and that man’s liberation is to be obtained by concentrating his attention on Iswara. Yoga is, therefore, the union of man’s mind with the Supreme Soul. When a man is perfect in profound meditations or “steadyings of the mind,” he gains a knowledge of the past and future, he has the power of shrinking into the form of the minutest atom, and gains mastery over Nature’s laws.
