Srila Visvanatha Cakravarti Thakura, quoting from the Vaisnava-tosani of Srila Sanatana Gosvami, says that the incident of Krsnas breaking the pot of yogurt and being bound by mother Yasoda took place on the Dipavali Day, or Dipa-malika. Even today in India, this festival is generally celebrated very gorgeously in the month of Kartika by fireworks and lights, especially in Bombay. It is to be understood that among all the cows of Nanda Maharaja, several of mother Yasodas cows ate only grasses so flavorful that the grasses would automatically flavor the milk. Mother Yasoda wanted to collect the milk from these cows, make it into yogurt and churn it into butter personally, since she thought that this child Krsna was going to the houses of neighborhood gopas and gopis to steal butter because He did not like the milk and yogurt ordinarily prepared.
