Hello Tookie

I believe the translation you're looking for is:
"ἡ του ἀνθροπου ψυχη ἀθανατος (ἐστιν)"

You could omit the "ἐστιν" to make it more powerful, and since it's a tattoo, to save some space.

My keyboard can't put spiriti on the starting vowels of the words, so I copied them from this Wiki page, which explains why they look a bit bigger.
