કપાળે કપાળે જુઈ મત, પણ રોટલા ટાણે એક મત.

kapāḷē kapāḷē juī mata, paṇa rōṭalā ṭāṇē ēka mata.

Literally: Every forehead has a different opinion, but at mealtime, there is one opinion.
What it means: People may disagree on everything else, but they all agree when it comes to their own self-interest or hunger.
