Been doing this for 20 minutes in the morning for a few decades now. It has had an impact. I am a rather “high gain” person emotionally. I now tend to notice emotions and observe them, which helps when they threaten to suck me into a self-perpetuating ruminative vortex. Also, it has made me gentler, and an easier person to be around. I’m now well aware that whatever disturbances occur, there will be echoes and resonances tomorrow morning during my sit! Now for a moment of honesty: this is a religious practice for me. A prayer that “landed” for me: “Lord, I ask to be a conduit of grace.”
