A devil Sumali sent his daughter Kaikasi to pursue Vishrava . They both , Vishrava and Kaikasi did Gandharva Vivah or simply Marriage resulting from Mutual love and consent between bride and the bridegroom . They gave birth to a demon male child who, as soon a he was born matured into a boy of 10 years He had devilish Powers with him and apart from that he had a very sharp mind also . this boy later renouned himself as Ravana and became the king of Lanka , the modern Sri Lanka. He was quite Extraordinary in his powers so he won over the gods and even conquered his own brother Kuber . he deprived him off his Pushpak viman as well as his wealth. .
