If you read the life of Shiva, the lord of all the yogis, you will see that after a long, long time -- sixty years of yoga -- he was tempted. Rishi Vishnamitri after forty years of yoga in the wilderness was tempted by the fair ones from Indra, the decree of whose court has always been to hinder the advancement in spirituality of the rare ones. Though Machandra was a very great yogi, he was tempted and taken away from the desert by Mahila, a Hindu queen, to her court, and there he was married and made a king, and among the flattering surroundings and luxurious environments he lost all his great powers achieved in the heart of the wilderness.
