I have to disagree with you. I don't see how Tarot etc. limits you. On the contrary Tarot helps to put you in touch with the plan, the Tao. If you are able to be in touch with that without any external aids, that's great and you have achieved what many others haven't. For others, however, Tarot is a great aid; it is not interfering with the flow, rather helping to put you in touch with it.
