Fear is such a powerful emotion for humans that when we allow it to take us over, it drives compassion right out of our hearts.
Letting go is never easy. The desire to have, to hold, to possess and to control is part of our nature. But the more powerful part yearns to learn the lesson of growth and openness; to enter the mystery of secret loving without desiring, to live in emptiness and stillness and therefore in a state of receptivity and readiness so that the quality of our being and "our being present to" are all that matter.
