The Light of one human being who discovers the Truth has been lighting human existence for thousands of years. Such is the power of a human being who realizes the Truth of who they are.
In my Deep Listening class at RPI, I always do an hour of energy exercises to start with. Then we do a listening meditation after that, after the body has been loosened up and warmed up and is ready. We do the listening. After that, there's the journaling of the experience, which they do each time throughout the semester to the point that I have them write a final paper on what they've experienced.
