Metaphysical Properties- Selenite is considered to be a 'mental body stone' which also opens, aligns and clears the aura bodies. It is able to transmit light, energy, and information; this maybe why many like to use it for channeling. It can be used as a scanning device for those of us who are not visually orientated to get an overall view of a person's light system to see the thought forms in their energy body.
You can direct the energy towards your client or yourself by physically pointing the Selenite towards your client and mentally aligning with its vibration to examine the thought forms that are stored within each energy body. From what I understand about Selenite wands it can be a powerful tool, but intent seems to be necessary in activating it.
