bala-grahas tatra vicinvati sisun
yadrcchaya nanda-grhe ’sad-antakam
dadarsa talpe ’gnim ivahitam bhasi
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
While searching for small children, Putana, whose business was to kill them, entered the house of Nanda Maharaja unobstructed, having been sent by the superior potency of the Lord. Without asking anyone’s permission, she entered Nanda Maharaja’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.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Demons are always busy creating disturbances and killing. But the child lying on the bed in the house of Nanda Maharaja was meant to kill many demons.
