The New Moon is when you are at your lowest...energy-wise. It is a good day to fast on lemon and water. Fast from sun-up until the next morning at breakfast, when you "break" the "fast."
... is the time between the New Moon and the day before the Full Moon. During this time the energy of the body moves into your higher centers (chakras). This is the time to bring new things, new people or new relationships into your life or to accelerate the progress of your special projects.
11 Days After New Moon
Yogi Bhajan taught that this is the day when you are in balance. The glandular system readjusts itself on this day. Your metabolism is changing, so if you eat very lightly (green foods) or if you live just on water and lemon today, your health will be perfect. Eat very lightly during the day. Eat only one meal and drink lemon and water the rest of the day.
You are naturally accelerated on a full moon. You are at your highest energy level. The secretions in your body will be at their maximum, so you don't want your energy being used to consume food. Save your energy to reconstruct yourself. Try to drink only liquids on this day. If you feel you must eat, drink only milk. (But, don't drink cold milk right out of the refrigerator. Milk should be brought to a boil. Allow the milk to foam up and then bring the heat down so the milk is on a slow boil for 5-10 minutes. While cooking it, you may add a pinch of ground turmeric, a pinch of black pepper, a cinnamon stick, or a few pinches of ginger to reduce any mucous causing side effect.)
... is the time between the Full Moon and the day before the New Moon. This is the best time to remove things, relationships or situations from your life that no longer serve you. It is not generally thought of as the best time to start a new project.
