This is Kate's tattoo, done by Cecelia at Seventh Son in San Francisco.
The quote is from two different sources:
No single thing abides, and all things are fucked up.
- The Transmigration of Timothy Archer by Philip K. Dick
No single thing abides; but all things flow.
Fragment to fragment clings - the things thus grow
Until we know and name them. By degrees
They melt, and are no more the things we know.
- On The Nature of Things by Lucretius
