The following quotation does not apply to my life so far, fortunately, but should it become relevant one day, I would like to remember it.
"Whenever tragic loss occurs, you either resist or you yield. Some people become bitter or deeply resentful; others become compassionate, wise, and loving. Yielding means inner acceptance of what is. You are open to life. Resistance is an inner contraction, a hardening of the shell of the ego. You are closed. Whatever action you take in a state of inner resistance (which you could also call negativity) will create more outer resistance, and the universe will not be on your side; life will not be helpful. If the shutters are closed, the sunlight cannot come in."
Eckhart Tolle, A New Earth - Awakening to your life's purpose, chapter "Ego: the current state of humanity".
