To become enlightment means viewing the world without any extreme opposites. Thinking about that a metaphor was created in my mind: Life is like a spinning disk. You are on the disk and the Universe is around you. You move closer to the center when you are giving up extreme opposites. The more far away are you from the center, the more delusion filled and distorted your view on the Universe becomes. Only in the middle can you view reality as it is. (But how you know where is the center? )
