Siddhasena

Siddhasena Divakara came upon a Linga temple in Ujjain. He slept at the temple with his feet towards the Linga, which is a symbol of Shiva. King Vikramaditya had him beaten for the sin on request of the devotees. However, with miraculous powers, Siddhasena Divakara made that the King's wife received the beating instead of him. He was then set free. He broke the Linga by raising his hand and an idol of Parshvanatha emerged from there.

Bhartruhari realized the fleeting nature of the pleasure from worldly objects, he wrote a poem about the incident which changed him in his Niti Shataka. (100 stanzas on Moral conduct)

"(She) whom on I contemplate, is not passionate for me, she loves another;
that whom she loves, loves another;
One whom he loves, loves another.
Refuse (disdain to) that woman, that man, Cupid, me."

Deep Vairagya (dispassion) arose in him, he gave up the desire for his wife, realizing his mistake he brought his brother back and crowned him, renouncing the world he lived rest of his life as an ascetic. Bhartruhari wrote Niti-Shataka and Vairagya Shataka during his later years.
