One day Kṛṣṇa wanted to enjoy a picnic lunch within the forest, and therefore He went out early into the forest with the other cowherd boys, accompanied by their respective groups of calves. While they were enjoying their picnic, Aghāsura, the younger brother of Pūtanā and Bakāsura, appeared there, desiring to kill Kṛṣṇa and His companions. The demon, who had been sent by Kaṁsa, assumed the form of a python, expanding himself to a length of eight miles and the height of a mountain, his mouth seeming to extend from the surface of the earth to the heavenly planets. Having assumed this feature, Aghāsura lay on the road. Kṛṣṇa’s friends, the cowherd boys, thought that the demon’s form was one of the beautiful spots of Vṛndāvana. Thus they wanted to enter within the mouth of this gigantic python. The gigantic figure of the python became a subject for their sporting pleasure, and they began to laugh, confident that even if this figure were dangerous, Kṛṣṇa was there to protect them. In this way, they proceeded toward the mouth of the gigantic figure.
