People believe that when they say "yes" to this moment, things won't change anymore. They're afraid that if they accept what is, whatever form this moment takes, they're going to be stuck forever in this moment that they don't like: this job or relationship or whatever situation they're in that they don't like. But this is not true.
Eckhart TolleTrue freedom and the end of suffering is living in such a way as if you had completely chosen whatever you feel or experience at this moment. This inner alignment with Now is the end of suffering. Is suffering really necessary? Yes and no. If you had not suffered as you have, there would be no depth to you as a human being, no humility, no compassion. You would not be reading this now. Suffering cracks open the shell of ego, and then comes a point when it has served its purpose. Suffering is necessary until you realize it is unnecessary.
Eckhart Tolle
