When Vasudeva understood from Nanda Maharaja that the mystery of Krsnas birth and His having been exchanged with Yasodas daughter was yet undisclosed, he was happy that things were going on nicely. By saying that Vasudevas daughter, his youngest child, had gone to the heavenly planets, Nanda Maharaja indicated that he did not know that this daughter was born of Yasoda and that Vasudeva had exchanged her with Krsna. Thus the doubts of Vasudeva were dispelled.
