The 'fall of man' is simply the shift from awareness to thinking.
Thought is a tool to use and let go of immediately; but clinging to thought is our 'Original Sin.' We were not created to become trapped in ideas and beliefs, a thought-world of conflicting opposites. This is eating from the Tree of the Knowledge of Good and Evil. We were created to eat from the Tree of Life, living awareness free of compulsive thinking.
To return to the Garden is to rest in the innocence of the still mind, empty like the blue sky, self-radiant, free from concepts. One root for the Hebrew word 'eden' means 'bliss.' Eden is the bliss consciousness of our original nature. It is what we are the moment we awaken in the morning, before the mind of yesterday returns.
