Truly, the edge is a subtle, fragile place. It is like listening to a whisper. As with anyone that whispers, the secret must be honored. When you do not honor a whisper, there is a loss of trust, You are no longer trusted as safe. If you break this trust it takes a long time to be trusted again. However, if you do prove yourself worthy you become a confidant. More secrets will be told. In learning to "touch the edge without bursting through it" your body begins to open up; slowly at first, but later in bursts.
The outcome is not the central goal. In experiencing the joy of efficient physical expression we find the gentle edge. We become the very embodiment of vitality.
