In truth, you Consciousness itself. Yet we fail to look at the obvious. Our bodies are reflections of this consciousness. The heart beats, blood circulates, and cells change because of consciousness. Yet because we believe in the body, we also believe in time.
Time is a fiction created by the linear brain to adjust to and survive changes.
It is like the earth rotating around the sun. We think of each rotation as a day, then a week, month and year. However, nothing is really happening except a circle of activity. You are not the wheel - you are the silent hub in the center that watches everything and is untouched by all that changes. This is the fear of the superficial self, which fears what it cannot understand.
