Just as the pure and fragrant lotus flower grows out of the mud of a swamp rather than out of the clean loam of an upland field, so from the muck of worldly passions springs the pure Enlightenment of Buddhahood. Even the mistaken views of heretics and the delusions of worldly passions may be the seeds for Buddhahood.
If a diver is to secure pearls he must descend to the bottom of the sea, braving all dangers of jagged coral and vicious sharks. So man must face the perils of worldly passion if he is to secure the precious pearl of Enlightenment. He must first be lost among the mountainous crags of egoism and selfishness, before there will awaken in him the desire to find a path that will lead him to Enlightenment.
There is a legend of a hermit who had such a great desire to find the true path that he climbed a mountain of swords and threw himself into fire, enduring them because of his hope. He who is willing to risk the perils of the path will find a cool breeze blowing on the sword-bristling mountains of selfishness and among the fires of hatred and, in the end, will come to realize that the selfishness and worldly passions against which he has struggled and suffered are Enlightenment itself.
