was virtually a formidable demon by name Kalanemi in human form. He
was a great dictator and relied more on muscle power than the
spiritual; and in tune with his inner venomous nature-rakshasa
swabhava, he usurped the throne, on hearing from the Akasavani that
his sister's eighth son would kill him. To prove the falsity of the
aerial voice and to establish his invincible power, he forthwith
imprisoned his sister Devaki along with Vasudeva, her husband,
setting aside all the reasonable pleas. Later, he put to sword
ruthlessly one after another, six children of the imprisoned couple.
In accordance with the divine plan, the seventh embryo was
transferred to Rohini, the first wife of Vasudeva, and the son thus
born was named SankarshanaBalararna, due to the fact of extraction
and transference of embryo.
The eighth child-the future Purana Purushothama was exchanged soon
after birth with Yasoda's daughter called Yogamaya, who miraculously
flew into air and became Durga, when Kamsa raised his sword to kill
in the routine way. Before melting into air, she predicted that his
Yama escaping from the prison was brought up safe elsewhere. From
then began a series of futile trails of Kamsa, and he left no means
un attempted to kill Krishna, his target.
