This saying in my local tounge

Which roughly translates to

“You small, I big , this thought of world is incorrect, A Thirsty man feels the the ocean is smaller than than a glass of fresh water”

Imagine above is a really Catchy rhyming.

I don’t think anyone will understand but here it is in local tounge trying to write the sound in English.

Tu nano, hu moto, e khyal jagat no koto. Tarsa ne to dariya karta loto lage moto.

Does it mean that one shouldn’t think of others as small or inferior? That one is seeing others as small because of their thirst for(or lack of access to) power or so?

It’s Gujarati

Thank you.
Is Gujarati similar to Hindi? Devnagiri script n all?
