When you meditate, you are a ground zero. You are at a reset point. You are in a non-judgemental loving state. You are receptive and free. Within meditation, you are vibing at the highest state of divine love. Meditation connects you to all things. So when you are at that state of mind, the universe, your guides, your fairy godmothers, your angels can download information to you and provide you healing without the human ego resistance to the magic.
So practice meditation. Be mindful of how you fall asleep, be mindful of how your mind works, be mindful of how you get information, be mindful of how you feel after or before, be mindful of which meditations work for you, either guided or just conscious breathing.
So as you integrate more and more of your energy with Reiki, you can also evolve your meditation skills so that you can fully utilize what this reiki energy offers you and your clients.
