રણ ચડા ઠાકારે, બહુ બતાવે બળ; રામ રણે આવશે, જખ મારે જેમલ.

raṇa caḍā ṭhākārē, bahu batāvē baḷa; rāma raṇē āvaśē, jakha mārē jēmala.

Literally: The Thakor who has entered the battlefield shows great strength; when Ram comes to the battlefield, Jaimal is left helpless;
What it means: Human pride and strength are useless when divine intervention or a far superior force takes over.
