સંધા દેવ તો બાળા ભોળા, હું તો માતા શીતળા, અંગ તો જાણે એવું કરું, કે જાણે કાળાં ઠીકરાં.

saṁdhā dēva tō bāḷā bhōḷā, huṁ tō mātā śītaḷā, aṁga tō jāṇē ēvuṁ karuṁ, kē jāṇē kāḷāṁ ṭhīkarāṁ.

Literally: All gods are innocent and simple, but I am Mother Shitala; I make the body look like black potsherds.
What it means: Harsh, unyielding forces inflict severe damage without showing mercy.
