A warrior in a grey cloak sits in meditation in a meadow, seen from behind, under a large pale moon.
The warrior sits with a straight back and lets the breath slow down. Thoughts come and go without being followed. This is stillness of mind.
Kepler-442 b is a real planet around a star cooler than the Sun, and its size comes from transit measurements. The meadow and the moon are invented.
