Book III, The Active Night, Chapter XXIX, The Fifth Kind of Goods in Which the Will has Joy
In The Ascent of Mount Carmel, Book III, Chapter XXIX, St. John of the Cross discusses the "fifth kind of goods" in which the will finds joy: the joy found in supernatural visions and spiritual revelations. He warns that while these visions might seem beneficial for spiritual growth, they can actually hinder the soul's journey toward union with God if the will becomes too attached to them. The soul must learn to let go of the desire for such extraordinary experiences, as they are distractions from a pure love of God, which should remain detached from any form of spiritual gratification. St. John emphasizes that the highest form of joy in God comes not from extraordinary visions or experiences but from a humble and simple faith, enabling true union with God beyond sensory or supernatural consolation.
