I would have to agree with Alikat,that Curezone is the place to come to learn how to fast. If you have not fasted in a while I would really recommend the Master Cleanse. I think that it is the easiest on your body ie.. it does not send your body into a major toxic shock, but yet it is very effective in cleansing your system.
We know that from the words of Soloman, that our sins come from our bowels. What we eat has alot to do also with our spirituality.We must work to keep ourselves clean. Happy fasting!
