The Lord said to Devaki and Vasudeva, “I now appear as Krishna, born of you, Devaki and Vasudeva, and if I have shown you this form of Visnu, it is for the sole purpose of convincing you that I am the same Supreme Person, who appears again, I could have shown myself as an ordinary child, but would you have understood then that I, God, the Supreme Person, I had descended into the breast of Devaki”?
“My dear father, my dear mother, you have therefore raised me many times as your child, with great love and affection, how could I not be satisfied with you and not feel obliged to you”?
“I promise you that this time you will return to the Spiritual Kingdom, the original Abode, because you will have ensured the perfection of your mission.I know that you have great concern for my Person and for that fear Kamsa.I therefore ask you to to take me immediately to Gokula and to exchange with the girl that has just been born Yasoda”.
Having thus spoken to his father and mother, the Lord transformed himself into a child like the others and remained silent.
As he had received the order from his Son, God in Person, Vasudeva undertook to bring him out of the room where He had appeared. At that moment, a girl was born from Nanda and Yasoda. This girl was none other than Yogamaya, the inner power of the Lord. By the influence of Yogamaya, all the inhabitants of Kamsa's palace, and especially the guards, were plunged into a deep sleep. All the doors, although barred and locked by iron chains, opened wide. Although the night was very dark, as soon as Vasudeva came out of Kamsa's palace carrying Krishna in his arms, he could see as clearly as in the daytime.
Krishna is like the radiance of the sun; where Krishna is, the illusory energy, comparable to darkness, can not remain. When Vasudeva wore Krishna, the darkness of the night dissipated. All the gates of the prison opened on their own. Arrived on the edge of the Yamuna, Vasudeva saw that the waters of the river were violently agitated by strong waves and covered with foam all over their extent. But the raging river dug in it an easy passage for Vasudeva, just as Sri Rama had done for the vast Indian Ocean. Thus, Vasudeva crosses the Yamuna River. Once on the other side, he went to Nanda Maharaja's home in Gokula, where he saw that all the herdsmen were sleeping soundly. So he went silently into the house, and there, without difficulty, he exchanged his Son with the girl who had just been born from Yasoda. Then he returned to Kamsa Prison and, still silently, placed the baby on Devaki's lap. At last he closed the chains again, so that Kamsa could not suspect that so many events had occurred that night.
Mother Yasoda knew that she had given birth to a child, but exhausted by the pain, she had fallen asleep. And when she woke up, she could not remember if she had discovered a boy or a girl.
