The more [the soul] approaches the vision [of God], so much the more does it see that the divine nature is invisible. It thus leaves all surface appearances, not only those that can be grasped by the senses but also those that the mind itself seems to see, and it keeps on going deeper until by the operation of the spirit it penetrates the invisible and incomprehensible, and it is here that it sees God. The true vision and the true knowledge of what we seek consists precisely in not seeing, in an awareness that our goal transcends all knowledge and is everywhere cut off from us by the darkness of incomprehensibility.
— Gregory of Nyssa
