નમન નમનમેં ફેર હે, બહોત નમે નાદાન; દગાખોર દુના નમે, ચિત્તા ચોર કમાન.

namana namanamēṁ phēra hē, bahōta namē nādāna; dagākhōra dunā namē, cittā cōra kamāna.

Literally: There is a difference in bowing; the naive bow too much; the deceiver bows double, like a thief's bow.
What it means: Excessive humility is often a sign of a hidden agenda.
