He who has tasted this light will understand what I am talking about. The soul is never sated with it, but the more it feeds on it, the more hungry it grows. It is a light that attracts the intellect as the sun the eye. Inexplicable, it yet becomes explicable through experience. This experience I have known or, more precisely, I have been wounded by it; but it commands me to be silent, even though my intellect would delight in speaking of it. ‘Pursue peace with all men and the holiness without which no one will see the Lord’ (Hebrews 12:14). Do this in order to acquire love and purity, for these are peace and holiness.
~St Philotheos of Sinai
