I have bought a bunch of these vials from Shilona, these are the most amazing tools for meditation! I like to roll it in my hand towards the sky as I repeat holy words, these help you make a LOT of progress if you are at a standstill, crossroads, big changes, etc. in your life. I was so ecstatic bout how well these worked that I did a little research and they said that some of these stones (like phenacite) can help heal your brain after PTSD, addictions, and other health issues that you would never even expect! LOVE THESE *FIVE STAR*
