શોભે સાના સમયમાં, વિણ સમય નહીં માન;

śōbhē sānā samayamāṁ, viṇa samaya nahīṁ māna;

Literally: It looks beautiful in its proper time, without time there is no respect;
What it means: Everything has its appropriate time and place, and actions performed out of season or inappropriately lose their value and respect.
