સોતી વાગે ચમચમ તો વીધા આવે ધમધમ.

sōtī vāgē camacama tō vīdhā āvē dhamadhama.

Literally: If it strikes while sleeping, it goes 'cham-cham', if it comes as knowledge, it goes 'dham-dham'.
What it means: Left blank on purpose. The scan is damaged here and the words are not certain enough to translate — English written over a guess would hide the guess rather than fix it. The Gujarati above is what could be read.

કહેવત સમુદાય (Kahevat Samuday) · read from the scan by machine — the Gujarati itself is unchecked · awaiting its meaning

Heard it differently, or know we've got the sense wrong? Tell us — that is exactly the kind of correction this needs.
