Mother Yasoda wanted to bind Krsna not in order to chastise Him but because she thought that the child was so restless that He might leave the house in fear. That would be another disturbance. Therefore, because of full affection, to stop Krsna from leaving the house, she wanted to bind Him with rope. Mother Yasoda wanted to impress upon Krsna that since He was afraid merely to see her stick, He should not perform such disturbing activities as breaking the container of yogurt and butter and distributing its contents to the monkeys. Mother Yasoda did not care to understand who Krsna was and how His power spreads everywhere. This is an example of pure love for Krsna.
