You are the human avatar of an angel of the 10th ray. You don't need substances (or psychic aids such as crystals) to claim your ability to receive images & written instructions (automatic writing).
It's time for all Indigos (10th ray) & Crystals (11th ray) to OWN their destined role as a new, advanced kind of spiritual healer/advisor. Here's all Indigos & Crystals need to do:
Meditate daily, e.g., see DreamWork & Meditation by Tara Ward..... Oracle cards (not Tarot) daily, e.g., Enchanted Map oracle cards by Colette Baron Reid... Automatic writing, weekly on Sundays, see Morning Pages exercise in Cameron's first book in The Artist's Way series.
