That's what I try to do, anyway. Just to tell the truth from your own heart. Other than that, there is no advice, except to add that I think it's very important not to analyse the ancient hereditary material that we've been handed down by the past. It's a mistake to assume that we can make some superior sort of judgement as to its meaning. Also, the notion that some bits of the human tradition are not somehow suitable, that some fairy tales, say, are not suitable for children - that is also a mistake.
Fairy tales have their own morals and theor own ethics.
Perhaps the violent element in some fairy tales is a sort of preparation for the violence and unfairness of the world. Such stories are much preferable to the junk pap on television or in movies like Star Wars and E.T. that are only imitations of our ancestral heritage. In order to avoid storytelling's becoming some sort of cutesy parlor activity, or some patronizing entertainment suitable only for children, it's important to maintain a string thread to its roots - to the personal voice, to one's commitment to the millenia that go before us, and to the unchanged mystery of the stories themselves. Stories are an inseparable part of the human dream.
