Frequent combing gives the hair more luster and makes it easier to comb; a soul that frequently examines its thoughts, words, and deeds, which are its hair, doing all things for the love of God, will have lustrous hair. Then the Bridegroom will look on the neck of the bride and thereby be captivated; and will be wounded by one of her eyes, that is, by the purity of intention she has in all she does. If in combing hair one wants it to have luster, one begins from the crown. All our works must begin from the crown (the love of God) if we wish them to be pure and lustrous.
– St. John of the Cross
