સોરઠા—નર તે ચતુર સુજાણ, સર અવસર ચૂકે નહીં;

sōraṭhā—nara tē catura sujāṇa, sara avasara cūkē nahīṁ;

Literally: A wise and clever man never misses his opportunity.
What it means: Intelligent individuals act immediately when a favourable moment arrives.
The English proverb Shah set beside it: Strike the iron while it is hot.Hoist your sail when the wind is fair.Every thing has its time and that time must be watched.
