The second guide on the warrior's path is represented by the analogy of an echo, which is connected with meditative awareness. When you try to take time off from being a warrior, when you want to let go of your discipline or indulge mindlessly in some activity, your action produces an echo. It's like a sound echoing in a canyon, bouncing back on itself, producing more echoes that bounce off one another. Those echoes or reflections happen all the time, and if we pay attention to them, they provide constant reminders to be awake.These echoes remind you to be on the spot, on the dot. However, you can't just wait for an echo to wake you up. You have to put your awareness into the situation. You have to put effort into being aware.
