‘The Secret Science: The Huna Knowledge of the Cosmic Energy Field’ (Scholarly Articles, Vol. 19) is a scholarly article both for neophytes and professionals on the subject of the Huna knowledge of the cosmic energy field. I first ask what the motivation might be to studying Huna at all and come to the conclusion that Huna is both a religion and a science, thus has prepared the path for the ultimate new age science that we now see emerging. The article elucidates that we have a heretic knowledge tradition also in our culture that did know and actively research about the cosmic energy field, as well as the human energy field. I analyze the works of Carl-Gustav Jung, Paracelsus, Swedenborg, Mesmer, Reichenbach, Reich, Lakhovsky and Burr on the subject.
