Fear is the absence of love. Just as darkness is the absence of light. Bring love, appreciation and understanding into the equation and fear no longer exists.
There is no need to understand everything. No need to control everything. One cannot begin to understand or control everything. Let go and be in the moment. We are here to experience being in the moment. Be in this moment and allow light into the darkness. Face fear with love, appreciation and understanding. Open the door so fear can dissolve.
