Some things never change, including the human need to connect with our creator. Prayer and meditation on the divine are techniques that have been used for millennia to grow in the knowledge of God.
"The Cloud of Unknowing" (Middle English: "The Cloude of Unknowyng") is an anonymous work of Christian mysticism written in Middle English in the latter half of the 14th century. The text is a spiritual guide on contemplative prayer in the late Middle Ages. The book counsels a young student to seek God, not through knowledge and intellection (faculty of the human mind), but through intense contemplation, motivated by love, and stripped of all thought.
