Reading the life of Shiva, the Lord of all the Yogis, one will see that after a long, long time of Yoga he was tempted. Likewise Vishvamitre Rishi, after a very long time 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 also was tempted and taken away from the desert by Mahila, a Hindu queen. Brought to her court he was married and made king, and among the flattering surroundings and luxurious environments he lost all his great powers achieved in the heart of the wilderness. It is easier to gain mastery in the wilderness, away from all temptations, but the mastery you gain in the world is of much more value; for the former is easily thrown down by a slight stroke, while the latter, achieved in the crowd, will last for ever.
