To arrive at perfect union, there is needed a total and perfect mortification of the senses and desires. The shortest and most effectual method of obtaining it is this: As to the senses whatever pleasing object may offer itself to them, unconnected with pure love to God, we should refuse it to them instantly, for the love of Jesus Christ, who in this life neither had nor desired to have any pleasure except to do the will of His Father, which He called His food. If, for example, there should arise a fancy or wish to hear or see things which do not concern the service of God or lead especially to Him, we should deny this fancy, and refrain from beholding or hearing these things; but if this is not possible, it is sufficient not to consent with the will. Then as to the desires, we should endeavor to incline always to what is poorest, worst, most laborious, most difficult, most unpleasant, and to desire nothing except to suffer and be despised.----St. John of the Cross
