SB 10.6.7, Translation and Purport

While searching for small children, Pūtanā, whose business was to kill them, entered the house of Nanda Mahārāja unobstructed, having been sent by the superior potency of the Lord. Without asking anyone's permission, she entered Nanda Mahārāja's room, where she saw the child sleeping in bed, His unlimited power covered like a powerful fire covered by ashes. She could understand that this child was not ordinary, but was meant to kill all demons.

Demons are always busy creating disturbances and killing. But the child lying on the bed in the house of Nanda Mahārāja was meant to kill many demons.
