need a translation for tattoo please

The second part is easy.
feed the soul --> animam pasce

The first part is difficult. As far as I can discover, there is no one Latin
word for "starve". You'd need something like fac ieiunium servare,
literally, "make <someone> perform a fast".

And "ego" is already a Latin word meaning "I". So you'd have to rephrase it
to capture what "ego" means in mordern English.

thank you!
maybe "make your pride hungry, feed the soul" ?
replece the word "ego" in "pride"

fac superbiam tuam esurire, animam pasce

Please read this.

thanks you george. maybe i will wait to someone else answer

I should probably mention that you are unlikely to get any further input
here. But there are other Latin forums or fora) out there to get additional
suggestions. I'd be happy to comment on any that you get.

My input may be of some use despite it not containing a translation.

Imagine a tattoo which says, "starve the ego feed the soul".

If the phrase is just a tad platitudinous and trite then what makes you think that it will be ennobled by translation into latin?

You are quite likely right.
