One of the greatest — if not the greatest — act of courage is the act of letting go.
Letting go of your personality, the false self, your personal history, and personal sense of self.
This process, as right as we intuitively sense it to be, is profoundly scary. We fear letting go because we don't know if we'll come back from going deeper and deeper into ourselves and into truth.
We have to wonder about that part of us that wants to hold on, and have great respect for it. And, when the time is right, let go of that final "security" measure.
What happens when we let go is we empty ourselves, which enables us to be filled up with purity.
