Anthony de MelloDo you want a sign that you're asleep? Here it is: you're suffering. Suffering is a sign that you're out of touch with the truth. Suffering is given to you that you might open your eyes to the truth, that you might understand that there's falsehood somewhere, just as physical pain is given to you so you will understand that there is disease or illness somewhere. Suffering occurs when you clash with reality. When your illusions clash with reality, when your falsehoods clash with truth, then you have suffering. Otherwise there is no suffering.

All of them were silent.
