For only those fully established in the practice of divine contemplation and virtue can have concourse with things strongly attractive to the senses without withdrawing their intellect from the contemplation of God and of God and from hymns and prayers to Him. Only such people can make these things the material and starting-point for raising themselves to God, and through this noetic movement towards God can totally master sensual pleasure. And even though the pleasure may be novel, and may be greater and more powerful because of its novelty, they will not allow their soul’s intelligence to be overcome by that which is evil, even though at the time it is regarded as good by those totally captured and mastered by it.
~St Gregory Palamas (Philokalia vol.4, p.369)
