पञ्चतंत्र - मित्रभेद - विमर्श

भये वा यदि वा हर्षे संप्राप्ते यो विमर्शयेत् |
कृत्यं न कुरुते वेगात् न स संतापमाप्नुयात् ||

- पञ्चतंत्र, मित्रभेद

He who ponders to think (and deliberates) when confronted with fear or extreme happiness and who would never react in a hurry will never be sad.

- Panchatantra, Mitrabheda
