This is the appeal of the East. The Western reliance on rationalism has failed. The East knows nothing of such distinctions. Eastern mysticism is monistic. The Christian believes in a personal God Who is separate from His creation.
Eastern thought makes no distinction between man and cosmos.
The name for this is monism. All is interrelated, interdependent and interpenetrating. Consider the ethical implications of such a view. The way you treat a person and the way you treat an animal are to be no different. This is why many advocates of monism are vegetarian.
