To learn to be always in a state of meditation means never to let your vital energy wane. You would never allow it to do so if it were certain that you were to die tomorrow. It wanes because you forget about death. Grit your teeth, fix your gaze, and observe death at this moment. You have to feel it so strongly that is seems as if it’s attacking you. Fearless energy comes from this. At this moment death is right before your eyes. It’s not something you can afford to neglect.
