It's time to not be led by earthly and materialistic needs like food and sleep, which are thought to 'keep us healthy.' We begin to idolize these earthly habits and put them before prayer, which actually dissolves and makes us run away from our eternal future with the Almighty God, which is being healthy and alive. As we listen weekly to the response of the readings in the liturgy 'Do not love the world or the things in the world. the world is passing away, and the lust of it; but he who does the will of God abides forever.' Earthly treasures which we spend buckets of time perfecting and increasing, are temporary. Although you may have heard this often, I think that's it's important to meditate on it.
Through riches, they could be easily stolen by a robber, where then are your treasures? In the Bible it says that your treasure is where your heart is, would you honestly like a spiritually hollow heart coated with gold? That is not a true heart. Let the inside of your heart account for its richness. If your wealth is your name and your money is robbed, then is your identity also stolen away with the robber? For your heavenly treasures, service, forgiveness, goodness, love, those are everlastingly stored in Heaven, where no one can steal them away. This preparation week is vital to think about this change in attitude, to have your life led not by your mind but by your spirit. Although you may not tell, but your spirit is hungry, so we must feed it. This is done by subtracting the earthly consumption to stop our earthly hunger. This act gives us self control; if you can prevent yourself from the luxuries of the world, like chocolate, then you can also prevent yourself from sinning, which is also earthly. Just as a sprinter must prepare and jog just before his race, so we must prepare and mediate before this fast. We all know what happens to a sprinter who doesn't stretch, he may injure himself during the race so that he cannot continue. Let this preparation week be our stretching to our mighty race of fasting.
With preparation, we can fast the whole fifty-five days.
