When the inhabitants of Vraja who had come from distant places heard the whole story of how Pūtanā had come and then been killed by Kṛṣṇa, they were certainly astonished, and they offered their blessings to the child for His wonderful deed of killing Pūtanā. Nanda Mahārāja, of course, was very much obliged to Vasudeva, who had foreseen the incident, and simply thanked him, thinking how wonderful Vasudeva was.
