If you've been interested in adding some Feng Shui practices into your home, there are some simple first steps, like adding light and ridding yourself of clutter and dark areas. If the path to your front door is not a curving one, at least guide it with potted plants to take a bit of a curve instead of hitting the front door head-on. Use live plants and not fake ones inside. You can also consider the use of amulets and incense. Here's some simple tips I use myself -
$4.99 amulet bag to carry in your pocket or purse on the go.
For $19.95 this house blessing incense kit is good. This particular brand of Feng Shui incense (Triloka) I have found to be so powerful that I sometimes have to back off on using it because it's that effective. I usually place a folded piece of paper with my wish under the incense holder and light the incense with a few quartz and amethyst stones on the holder. It sounds rather woo-woo, but I cannot explain why it seems to help so much.
This shop is filled with amulets and idols that will be helpful and very inexpensive.
For a great book on feng shui and how to keep your house free of bad spirits, consider "Confessions of a Feng Shui Ghost-Buster" by Anna Maria Prezio. It is fantastic!
