Look at every path closely and deliberately. Try it as many times as you think necessary. Then ask yourself and yourself alone one question. This question is one that only a very old man asks. My benefactor told me about it once when I was Young. And my blood was too vigorous for me to understand it. Now I do understand it. I will tell you what it is: does this path have a heart? If it does, the path is good. If it doesn't, it is of no use.
Jack KornfieldThe unawakened mind tends to make war against the way things are. To follow a path with heart, we must understand the whole process of making war within ourselves and without, how it begins and how it ends. War’s roots are in ignorance. Without understanding we can easily become frightened by life’s fleeting changes, the inevitable losses, disappointments, the insecurity of our aging and death. Misunderstanding leads us to fight against life, running from pain or grasping at security and pleasures that by their nature can never be satisfying.
