"Saint Simeon the New Theologian was born in the year 949 in the city of Galatea (Paphlagonia), and he was educated at Constantinople. His father prepared him for a career at court, and for a certain while the youth occupied a high position at the imperial court. When he was fourteen, he met the renowned Elder Simeon the Pious at the Studion Monastery, who would be a major influence in his spiritual development. He remained in the world for several years preparing himself for the monastic life under the Elder's guidance, and finally entered the monastery at the age of twenty-seven.
St Simeon the Pious recommended to the young man the writings of St Mark the Ascetic (March 5) and other spiritual writers. He read these books attentively and tried to put into practice what he read. Three points made by St Mark in his work "On the Spiritual Law" (see Vol. I of the English PHILOKALIA) particularly impressed him. First, you should listen to your conscience and do what it tells you if you wish your soul to be healed (PHILOKALIA, p. 115). Second, only by fulfilling the commandments can one obtain the activity of the Holy Spirit. Thirdly, one who prays only with the body and without spiritual knowledge is like the blind man who cried out, "Son of David, have mercy upon me (Luke 18:38) (PHILOKALIA, p. 111). When the blind man received his sight, however, he called Christ the Son of God (John 9:38).
St Simeon was wounded with a love for spiritual beauty, and tried to acquire it. In addition to the Rule given him by his Elder, his conscience told him to add a few more Psalms and prostrations, and to repeat constantly, "Lord Jesus Christ, have mercy upon me." Naturally, he heeded his conscience.
Durint the day, he cared for the needs of people living in the palace of Patricius. At night, his prayers grew longer and he remained praying until midnight. Once, as he was praying in this way, a most brilliant divine radiance descended upon him and filled the room. He saw nothing but light all around him, and he was not even aware of the ground beneath his feet.
It seemed to him that he himself became light. Then his mind rose upward to the heavens, and he saw a second light brighter than the light which surrounded him. Then, on the edge of this second light, he seemed to see St Simeon the Pious, who had given him St Mark the Ascetic to read.
