Our capacity to choose changes constantly with our practice of life. The longer we continue to make the wrong decisions, the more our heart hardens; the more often we make the right decision, the more our heart softens – or better perhaps, comes alive.
Each step in life which increases my self-confidence, my integrity, my courage, my conviction also increases my capacity to choose the desirable alternative, until eventually it becomes more difficult for me to choose the undesirable rather than the desirable action. On the other hand, each act of surrender and cowardice weakens me, opens the path for more acts of surrender, and eventually freedom is lost.
