Vishvakarma collected all the beauty from the Triloka and created an apsara named Tilottama, who was named so because she was created by bits and pieces of gems.
Tilottama’s beauty was so extraordinary that all beings were mesmerised by her. She was directed by Lord Brahma to distract the two asura brothers, Sunda and Upasunda, in a way that she would create a rift and turn them against each other.
As Sunda and Upasunda were drinking along a riverbank in the Vindhya Mountains, Tilottama appeared. When the asura brothers saw Tilottama’s radiant beauty, they became mesmerised and wanted to marry her, and this was when their unity broke.
Each brother claimed Tilottama for himself and neither was willing to let her go. Slowly, their affection turned into possessiveness, and soon into rage, which led to the brothers attacking one another.
A terrible duel took place between the two brothers, and finally, the brothers killed each other. Their unity made them invincible, but the rivalry over a woman became the cause of their destruction.
