Naran
The Black Tourmaline transmutes all the negative energy in our situation.
The good news is it need not be cleansed with rock water salt water like you do with crystals, as it has the capacity to cleanse itself.
So whatever you need, write it as you want something to happen – I mean your wish list (one wish per paper). Keep the stone over a single paper.
Every day morning look at the paper and then keep the stone once again on it.
As soon as your desires are fulfilled, drench the paper in water and tear it off.
