The feast of the Holy Ghost is celebrated in the substance of the soul, which is inaccessible to the devil, the world, and the flesh; and therefore the more interior the feast, the more secure, substantial, and delicious. For the more interior it is, the purer it is; and the greater the purity, the greater the abundance, frequency, and universality of God s communication of Himself; and thus the joy of the soul and spirit is so much the greater, for it is God Himself Who is the author of all this, and the soul doeth nothing of itself…  –St John of the Cross ‘Living Flame of Love’
