If the Universe had a superhero, and that superhero had a cosmic decoder ring, it would be made from a polished sphere of aubergine banded Sugilite (or maybe from just the tiniest sliver of this potent and vibrant mineral!). Sugilite taps you directly into your nervous system, boosting your innate ability to feel the life forces at work in the world around you, while simultaneously helping you recalibrate the worlds within you. Quiet that noisy brain, Sugilite advises. Your body is an instrument of knowing. When you pay attention to it, you’ll come back into balance — mind, body, emotions, and spirit. What makes your breathing smooth out? What makes your arms get goose bumps? Feel in order to know.
Ritual 
Our brains think and rethink, often sending us into saber-toothed tiger panic when all we’re really running from are the ups and downs of daily life. Sugilite guides you to redistribute this mental energy, letting it flow down through the axons of your nervous system, invigorating your whole being and helping it come into balance.
Your brain is a bit like a child who wants attention. Just like with a child, you can notice its ranting without reacting. When you notice your brain on overdrive, imagine the energy created by all that mental processing as a ball of purple light. Study it, becoming familiar with the way it moves and sparks. Then gently and slowly imagine the energy flowing down the pathways of your nerves, bringing life and feeling to your entire body. From this place, see what your body knows.
Reflection
In parts of Asia, Sugilite has become known as an anti-cancer stone, thought to vaporize tumors in a single bound. Notice how you think about illness, whether it’s cancer or any other disease. Do you feel like it’s a part of you or separate from you? When you become ill, do you feel like you deserve to be suffering?
Imagine having a cosmic decoder ring that lets you see the energy signature of each illness. Can you visualize unbraiding the energy of illness from your life force, gently changing the vibration of each of your cells?
The place of true healing is a fierce place. It’s a giant place. It’s a place of monstrous beauty and endless dark and glimmering light. And you have to work really, really, really hard to get there, but you can do it.
