In plain words: All of nature exists for the sake of the Self. Nature has no light of its own, just as the moon only reflects the sun. Its only purpose is to help the Self become free.
Nature has no light of its own. As long as the Purusha is present in it, it appears as light. But the light is borrowed; just as the moon's light is reflected. According to the Yogis, all the manifestations of nature are caused by nature itself, but nature has no purpose in view, except to free the Purusha.
Namaste.
A calm guide to life, the mind and the old teachings.
