If you are performing indoors, make sure that you are in a quiet place where you won't be disturbed. Clean the floor and area physically. Then take your Ritual Broom, and magickally cleanse the area.
Move the broom lightly across the floor, barely touching the floor, and visualize all the negativity and psychic clutter being swept away.
You can also scatter Salt mixed with herbs (Thyme, Rosemary, Frankincense, or Sage) to cleanse the room with the enegies contained within them.
You can also play a musical instument using ascending scales to purify. You can burn a clearing incense like Frankincense, Myrrh, Sage, Thyme, or Rosemary.
You can use any one or combinations of these to cleanse your ritual area. If you are performing outdoors, there is very little cleansing to be done. A light sweeping with the ritual broom is usually all that you need to do.
Purification of Yourself
This is simply putting yourself in the right mood and to put your focus on the ritual you are about to perform. You can play soft relaxing music and light candles and incense.
You can take an ritual bath. A ritual bath is a relaxing bath with bath oils and natural bath salts. For a real good effect, put candles and incense around the bathtub and just enjoy yourself.
When you're done with the bath, you might annoint yourself with Frankincense or Sandalwood Oil and sit down and meditate for a little while. Whatever it is you do, the point is to forget the stresses of life and focus on the ritual.
