When you see someone who is different than you or antagonistic towards you, do negative (critical, exploitative, dismissive, aggressive, etc.) thoughts/feelings automatically arise in your mind? When you sleep, do dark dreams arise? Do you feel urges to go watch aggressive TV shows or to listen to angry or depressive music?
That is the unconscious level at which people need to work on becoming better — more kind, compassionate, patient, tolerant, peaceful, content, etc. — because today’s conscious thought-choices plant the seeds for tomorrow’s unconscious feelings, and conscious thoughts, words, and deeds often take their cues from unconscious whispers. It’s a cycle. We need to keep a good tone to our minds.
If your mind were your living room, how would that room’s mood feel, and who/what would be welcome there?
