Paradox

One thing is all things

And all things are one

Big things are thin

And up will be down

Relativity is key

Also, a lock

Healthy men bleed

An eternal paradox

Limbo is real

But also is fake

A tricky idea

Yet simple, and great

A real complex head

Can’t grasp what is simple

It only can read

And question the riddle

Be dumb, do not think

But think to be dumb

One thing is all things

And all things are one
