See the first line of my signature. While not so much an allegory or parable, in Druidic traditions we use something called triads, which are three-fold says of wisdom. The second is a well-known one that I did not make, but the first is my own. A lesson about the power of story - the power of the bards - something that is grossly underestimated by most in the culture that surrounds me. We don't think about how the narratives we tell shape how we see and define reality, and how in turn that shapes who we are, how we behave. Often, we don't even recognize that we are telling stories to ourselves.
