કારજ સહાયતા વિના, કરી શકે નહીં કાય;

kāraja sahāyatā vinā, karī śakē nahīṁ kāya;

Literally: Without help, work cannot be done; say, what can a hammer do if there is no handle?
What it means: Tools and people are useless without the necessary components to make them functional.
The English proverb Shah set beside it: No flying without wings.
