TRANSLATION

" 'Although Krsna is beyond sense perception and is unmanifest to human beings, he takes up the guise of a human being with a material body. Thus mother Yasoda thought Him to be her son, and she bound Lord Krsna with rope to a wooden mortar, as if He were an ordinary child.'

This verse from Srimad-Bhagavatam (10.9.14) is in reference to Lord Krsna's exhibiting Himself like an ordinary child before mother Yasoda. He was playing like a naughty boy stealing butter and breaking butter pots. Mother Yasoda became disturbed and wanted to bind the Lord to a mortar used for pounding spices. In other words, she considered the Supreme Personality of Godhead an ordinary child.
