An image that won't leave my head is a supreme martial artist meditating on the surface of a star

meditating under a waterfall for when you're too powerful

meditating while one of these things washes over you

I actually did have a mental image of Astra from University Excalibur, far in the future, asleep in the middle of a star.

Just the movement of the solar flares keeping the same time as her softly, peacefully breathing in and out. Unclear if this is some kind of "mighty ancient power in eternal sleep" thing or if she's just taking a nice nap.
