Cleansing the Spirit- to wash away curses, negative feelings, & worries. May help cleanse against demons.
Once you have found a quiet area, either turn off the lights or leave them on. Put on some soothing music. I recommend the 'Linkin Park: In the End: Soothing, Relaxing Music' that can be found on Youtube.
Put a blanket on the floor, or get a seat, & the sit cross-legged on it. Imagine your mind layed out in front of you, in clear water in a white spotless bowl. That water washes all the bad things wawy from your mind.
Do this about once or twice a day, & do it for about twice the song.
