Nourished Energy

Something I have been speaking about recently when it comes to Reiki is really understanding what the reason is for having different tools in our Reiki practice. Reiki is about returning to our truth, coming to that space of oneness, connection. Why do we need so many tools? Why do we need the precepts? Why do we have hand positions? Why are we taught symbols? If Reiki is just about being, shouldn't we just sit quietly and meditate?
