The best way to effect change in oneself and in the world is to withdraw one’s energy from the common, programmed pool, and be a beacon of Peace/Light/Love. The more of us who are cells of sanity in the body of humanity, the greater the Light—and the cancer of the Illusion/madness will be diminished and eradicated.
Whatever one needs to know comes to one’s attention. Rather than participating in and supporting the media-generated chaos, maintain Awareness; enjoy and support a Higher Reality.
Try giving yourself a 'news' break for a week and see what happens when you re-engage. If you’ve been focused and mindful, the dissonance will be obvious.
"Be the change you want to see in the world" by mastering the quality of your energy. It's a moment-by-moment exercise.
