A white-furred warrior sits with one leg extended and one palm raised beside a frozen lake, under green aurora.
One leg stretches out along the ground while the other stays folded. The raised palm lifts slowly with the in-breath and lowers with the out-breath. Slow stretching like this is part of strength of body.
Kheln is invented. An aurora forms when fast particles strike the upper atmosphere and make its gases glow, as oxygen and nitrogen do on Earth.
Practice
Raise one palm as you breathe in and lower it as you breathe out.
