When Lord Kṛṣṇa was enjoying His childhood pastimes with His boyfriends, one Aghāsura demon became very impatient. He was unable to tolerate seeing Kṛṣṇa play so happily, and therefore he appeared before the boys intending to kill them all. This Aghāsura was so dangerous that even the denizens of heaven were afraid of him. Although the denizens of heaven drank nectar daily to prolong their lives, they were afraid of this Aghāsura and were wondering, "When will the demon be killed?" The denizens used to drink nectar to become immortal, but actually they were not confident of their immortality. On the other hand, the boys who were playing with Kṛṣṇa had no fear of the demons. They were free of fear. Any material arrangement for protecting oneself from death is always unsure, but if one is in Kṛṣṇa consciousness, then immortality is confidently assured.
The demon Aghāsura appeared before Kṛṣṇa and His friends. Aghāsura happened to be the younger brother of Pūtanā and Bakāsura, and he thought, "Kṛṣṇa has killed my brother and sister. Now I shall kill Him along with all His friends and calves." Aghāsura was instigated by Kaṁsa, so he had come with determination. Aghāsura also thought that when he would offer grains and water in memory of his brother and sister and kill Kṛṣṇa and all the cowherd boys, then automatically all the inhabitants of Vṛndāvana would die. Generally, for the householders, the children are the life and breath force. When all the children die, then naturally the parents also die on account of strong affection for them.
