“Me” is an appearance that tries to manipulate, control, hold on to, and get involved with other appearances. It’s an activity, a verb, an energetic movement. A bird flying across the sky.
Why is noticing this so powerful? Because there can be a realization that if you are what is seeing the appearance, the appearance, regardless of what it is, can’t be you. It’s simply a passing appearance.
Bird’s, stars, comets, sun, rain, snow, airplanes, etc. pass through the sky 24/7, yet the sky remains ever unstained by anything that passes through it.
