After Kamsa had killed six of Devaki’s
babies, Devaki became pregnant again. This time she was filled with
effulgence and gladness, and felt that the Supreme Personality of Godhead
was within her. This was Balarama, who is the expansion of Krishna and
who, in another form, serves Krishna’s form of Vishnu as the serpent
bed. He came first, in the mood of serving Krishna, to purify the womb
so that Krishna could come next.
But Devaki did not give birth to Balarama. Krishna made an arrangement
to transfer Balarama to the womb of Rohini, another wife of Vasudeva
who had been sent to his brother Nanda, the king of the cowherd village
of Vrindavan. Balarama was therefore born in Vrindavan, and everyone
thought Devaki had had a miscarriage.
