In the Eastern world, such as in China and India, the moon is actually the primary consideration in studies of astrology. The moon signs and cycles are used to determine the best time for activities, and is a part of daily life. This may seem backward to some, but actually results in more accurate predictions in many cases than Western astrology can ascertain.
I'm not anti-science, in fact I think our world has only improved because of it. But science should be no less immune from a serious reality check than was the church in the dark ages. I believe in the bible , and I'm sure it gives us only a very short time to the second coming of Christ. But even at that I would never put the bible against science. I am satisfied that science is the book of how, and the bible is the book of why.
The waning of the moon is the period that runs between the Full Moon and the New Moon. It supports the energy of letting go, releasing, moving away from situations you've outgrown. It is a great time for working heavily on any releasement work such as clearing addictions and difficulties. It is also the perfect time to do a Spring Cleaning, going through your things and throwing out anything you no longer use, getting your hair cut, in fact, anything to do with getting rid of stuff.
