I've now read most of what's out there in the intuitive communication arena, as well as a good deal of related material. There are very few standouts. Marta Williams is one of them. I like Marta's approach to writing about intuitive communication topics; it's refreshingly direct and concrete.
Her latest book provides plenty of material to ponder in terms of how our relationships with our animals--as individuals and as communities--are a reflection of our patterns of spiritual/psychological disharmony (and harmony, though that's not as fully discussed). The book seems to assert that what is most often reflected is the harmful thinking/behavior that we aren't recognizing in ourselves. Marta and the people whom she quotes here offer the reader the option of learning how to see what our animals may be reflecting to us, so that we can change what needs changing for our well-being and that of our fellow creatures.
Marta has, in her typical style, gone on from there to offer specific tools to use for effecting changes, both in ourselves and the world around us. Her techniques are flexible enough to be adaptable to the diversity of her readers' lives, but still specific and concrete enough to be practicable by even a novice of intuitive work.
If there is one criticism I have to offer, it's that, given her scientific background, I hoped Marta's work would stand out in the intuitive communication field, for taking a genuinely objective approach to her topic, but it falls surprisingly short there. Like all the other I.C. authors I've read, her eagerness to convince frequently leads her to explain a phenomena with a completely subjective theory, which is held to be proven by yet another subjective theory.
I.C. is a pretty subjective field in many ways, of course, but that doesn't mean we can't question our assumptions about it, or engage in honest, rational discussion about the theoretical nature of any attempt to explain intuitive experiences. Probably the reluctance of writers to do this stems from the intensity of the criticism often leveled at the I.C. community. It's hard to admit your weaknesses in front of your enemies, but I'd like to see us ask ourselves, out loud, the questions that otherwise become criticism of I.C. If we are so attached to our own assumptions that we fear to do this kind of exploration, our closed-mindedness differs not at all from that of persons in the scientific establishment, or conservative religious establishment(s), or elsewhere, that are eager to discredit I.C. for similarly fearful reasons.
Stepping off my soapbox now...
I still highly recommend Marta Williams' "My Animal, My Self" as an engaging, singular introduction to the phenomena of mirroring between humans and nature. I gained some powerful insights from it, and I intend to go back and reread it more slowly.
