What's passions with a hawk's eye. Don't let them dominate your life. Look only to God to be the ultimate goal. Any other passion can lead to pain. But don't confuse a passion with something that is evil in it self. There is nothing wrong with eating, or sleeping, or having a bit of rest, vacation, and relaxation. What is harmful if these things take over our thoughts and wants.
In the end we enjoy thinking about them and yarning for them more then we actually enjoy the activities. How many times we keep thinking about going on vacation only to be disappointed and aggravated when we are there. Therefore don't let anything that is good in itself become a passion that will begin to torture you from inside and take away your attention to your present moment and your current life. They key to our life is to fight with our passions so that our good intentions and natural needs do not lead to sin.
