"After trying various kinds of ascetical practices, both in the monastery and then in the wilderness, he began standing on pillars of progressively greater height, and heroically persevered in this for more than forty years; the greater part of this time he spent standing upright, even when one of his feet became gangrenous, and other parts of his body gave way under the strain. He did not adopt this strange way of life out of vainglory, a charge that some of his contemporaries made against him at the first: because he was already famous for his asceticism and holiness before ascending his first pillar (in Greek, style, whence he is called "Stylite"), many pious people came to him wishing to touch his garments, either for healing or for a blessing; to escape the continual vexation they caused, he made a pillar about ten feet high, and then higher and higher, until the fourth and last was about fifty feet high. The Church historian Theodoret of Cyrrhus, an eyewitness of his exploits who wrote of him while Symeon was yet alive, called him "the great wonder of the world." God gave him the grace to persevere in such an astonishing form of asceticism that multitudes came to see him from Persia, Armenia, South Arabia, Georgia, Thrace, Spain, Italy, Gaul, and the British Isles. Theodoret says that he became so famous in Rome that the Nomadic Arabs by the thousands believed in Christ and were baptized because of him; the King of Persia sent envoys to inquire into his way of life, and the Queen asked to be sent oil that he had blessed. He also was a great defender of sound doctrine, and confirmed the Orthodoxy of the Holy Council of Chalcedon for many who had been beguiled by the teachings of the Monophysites, including the Empress Eudocia, widow of Theodosius the Younger. After a life of unheard-of achievements and struggles, he reposed in peace at the age of sixty-nine, in the year 459."

Simeon the Stylite, the first of the pillar-dwellers,
We should use all that is necessary in this world for the cultivation of our souls, for when death separates us from this world we will take nothing to the other world except our souls, in whatever state they have been formed here. When he was eighteen, St. Simeon the Stylite was so concerned about the salvation of his soul that one day he fell face down on the earth and prayed to God that He would show him the path of salvation. And lying thus in prayer for a long time, he had a vision that he was digging a trench for a foundation and, exhausted from digging, stopped to catch his breath. A voice spoke to him, saying: ``Dig deeper!'' Then he began, with greater labor and effort, to dig yet deeper. Again he stopped to catch his breath. But again he heard the voice: ``Dig deeper!'' He again began to dig, with even greater labor and effort. At this the voice spoke to him again: ``Stop, it is sufficient! Now build what you wish to build; for without labor, you will succeed in nothing.'' Those who labor little, and build the life of their soul on sensual shallowness, build on sand, which cannot uphold anything, even in this transitory world-and even more so in eternity.

Thou becamest a pillar of patience and didst emulate the Forefathers, O righteous one: Job in his sufferings, Joseph in temptations, and the life of the bodiless while in the body, O Symeon, our righteous Father, intercede with Christ God that our souls be saved.
Thou soughtest the heights, though parted not from things below; thy pillar became a chariot of fire for thee. Thou becamest thereby a true companion of the angelic host; and together with them, O Saint, thou ceaselessly prayest Christ God for us all.
