Hello Love:-) Thank you for your question.
Smoky Quartz is an awesome crystal to work with in Meditation and also Healing.
According to Doreen Virtue it is associated with the Archangel Michael and it works as an anchor to the Earth while working in upper dimensions and doing consciousness expanding work.
It's properties are grounding, protective and gently cleansing: eliminating fear and negative energies.
Simply holding your smoky quartz wand during meditation/ prayer will help balance yang energy, clear your space and form a protective forcefield around you.
You may run reiki energy (or other healing energies) through your wand by directing your intentions and simply asking the stone to serve your purpose.
As a practitioner I use the wand to direct stuck energy in my client out of the auric field and to define energetic pathways.
If you are doing lots of crystal work I would recommend you pick up the book "Love is in the Earth"- a Kaleidoscope of Crystals by Melody. It is considered to be the "bible" of the Metaphysical properties of stones and crystals. I am sure you will love it and find even more creative ways to use your new "toy".
Hope that helps:-)
warmly,
Aeriol
