A tiny figure sits at the end of a dark basalt courtyard, with the planet's own rings arching across the sky.
The figure sits at the open end of a stone courtyard with the legs crossed and the hands in the lap. The eyes are half open and the attention stays on the breath. That steady attention is stillness of mind.
Planetary rings are many small particles circling near a planet's equator, so from the ground they arc across the sky. The dark gap is where the planet's shadow falls on them. Thesra is invented.
Practice
Sit with half-open eyes and count your breaths up to fifty.
