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

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

Literally: All other gods are innocent and simple, but I am Mother Shitala; I make the body look like black potsherds.
What it means: Said of a ruthless or destructive force that leaves devastating, permanent marks, unlike gentler entities.
