"The Self in you is the same as the Self Universal. Whatever powers are manifested throughout the world, those powers exist in germ, in latency, in you.... If you realize the unity of the Self amid the diversities of the Not-Self, then Yoga Will not seem an impossible thing to you."

When this love, the heavenly gift of Nature, appears in the heart, it removes all causes of excitation from the system and cools it down to a perfectly normal state; and invigorating the vital powers, expels all foreign matters- the germs of diseases-by natural ways (perspiration and so forth). It thereby makes man perfectly healthy in body and mind, And enables him to understand properly the guidance of Nature.
