વહાણ, વરસાદ ને વિવાહ, એ ત્રણ આવ્યાં ભલાં;

vahāṇa, varasāda nē vivāha, ē traṇa āvyāṁ bhalāṁ;

Literally: A ship, rain, and a wedding—these three are good when they have arrived.
What it means: Certain events and blessings are only reliable and worth celebrating once they actually happen.
The English proverb Shah set beside it: Ships, rain and weddings are best when they arrive.
