“Man’s body participates in the theoria of God, but he sees the Light and hears God’s voice only after his perceptive faculties have been transfigured by divine grace. His senses are transformed in order to see the Light” (Met. Hierotheos, 2010, The science of spiritual medicine, p. 458). Not everyone can see the Divine uncreated Light because “that Light is invisible to those whose senses have not been transformed by the Holy Spirit” (ibid., pp. 458-459). This is the same process that the apostles Peter, James and John underwent on Mount Tabor during the Transfiguration of Christ.
