the spacious sky

taken from a moving train...

The substance of mind is the substance of heaven. A joyful
thought is an auspicious star or a felicitous cloud. An angry
thought is a thunderstorm or a violent rain. A kind thought is a
gentle breeze or a sweet dew. A stern thought is a fierce sun or an
autumn frost. Which of these can be eliminated? Just let them pass
away as they arise, open and unresisting, and your mind merges with
the spacious sky.
