Works best when used in an essential oil vaporiser/diffuser. (Do NOT put in a spray) This should be clean, filled with regular water and add just a few drops of Astral Clear. It may be left in a corner in the room, and kept going for many hours. This method is of course unobtrusive and very useful in treatment rooms. It works in most electronic diffusers as well as in candle powered ones. (Follow the instructions for your electronic diffuser). To shift really deep dark stuff keep it going for days, even weeks, it really gets through it!
Astral Clear may also be used to cleanse the personal aura, placing a few drops on the palm of one hand, rubbing hands together once, then passing through the whole aura from top to bottom, as with Crystal Clear.
Serious Cleansing: for really tough clearing of deeply resistant or ingrained negative energies, use with a crystal, adding a couple of drops to a clear quartz which is simply programed to send the essence into the space.
