બિના તેગકે શૂરવીર, કરે કહા જો ધાય; જ્યું જલ બાહેર મીનકું, પેશ કચ્ચુ નહીં જાય.

binā tēgakē śūravīra, karē kahā jō dhāya; jyuṁ jala bāhēra mīnakuṁ, pēśa kaccu nahīṁ jāya.

Literally: What can a brave warrior do if he runs without a sword? Just as a fish outside of water has no way forward.
What it means: Even the most capable person cannot succeed or act effectively without the necessary tools or resources.
