* 7 most referred to chakras

This is very basic information, but if you are a novice reaching out for more knowledge, I'd recommend:

1. Choose a crystal you feel instinctively drawn to
2. Before reading up on it, cleanse it first, then..
3. Take it to bed and ask for your dream to reveal how the crystal can help you.
4. Read about the crystal, see how your dream (if you have one) relates to what you read
   

I've had the most amazing revelations doing this !
