Insight-Rule 17

The whole universe is contained within a single human being you. Everything that you see around, including the things that you might not be fond of and even the people you despise or abhor, is present within you in varying degrees. Therefore, do not look for Sheitan outside yourself either. The devil is not an extraordinary force that attacks from without. It is an ordinary voice within if you set to know yourself fully, facing with honesty and hardness.
