Bhesh dekh na pujiye, puchh lijiye gyan

Bina kasauti hot nahi, kanchan ki pehchan

भेष देख ना पुजिये, पूछ लीजिये ज्ञान |

बिना कसौटी होंत नाही, कंचन की पहचान ||

Dont go after the outward appearance. See whether he has the right
knowledge. A goldsmith cannot verify the purity of gold without
putting it to test.
