Ordered by the Supreme Personality of Godhead, Vasudeva took his son from the prison. The night was very dark, but as soon as Vasudeva picked Kṛṣṇa up and went out, he could see everything just as in the sunlight.
By the influence of Yogamāyā, all the prison guards fell fast asleep, their senses unable to work, and the other inhabitants of the house also fell deeply asleep. When the sun rises, the darkness automatically disappears; similarly, when Vasudeva appeared, the closed doors, which were strongly pinned with iron and locked with iron chains, opened automatically. Since the clouds in the sky were mildly thundering and showering, Ananta-nāga, an expansion of the Supreme Personality of Godhead, followed Vasudeva, beginning from the door, with hoods expanded to protect Vasudeva and the transcendental child.
Because of the constant rain sent by the demigod Indra, the River Yamunā was filled with deep water, foaming about with fiercely swirling waves. But as the great Indian Ocean had formerly given way to Lord Rāmacandra and allowed Him to construct a bridge, the River Yamunā gave way to Vasudeva and allowed him to cross.
When Vasudeva reached the house of Nanda Mahārāja, he saw that all the cowherd men were fast asleep. Thus he placed his son on the bed of Yaśodā, picked up her daughter, an expansion of Yogamayā, and then returned to his residence, the prison house of Kaṁsa. Vasudeva placed the female child on Devakī's bed, replaced the iron shackles on his legs, and thus remained there as before.
Exhausted by the labor of childbirth, Yaśodā was overwhelmed with sleep and unable to understand whether a male or a female child had been born to her.
