Jaap van Etten holds a Ph.D. in Biology with a specialty in Ecology. About 20 years ago his life changed dramatically, shifting the focus in his life more towards spirituality. He believes that science and spirituality need to be integrated again. This led him to the study of metaphysical ecology: the study of the interaction between the human (subtle) energy system and the (subtle) energy systems in its environment. He has summarized the results of his studies in "Gifts of Mother Earth," that was published in March 2011.
In 1994 Jaap had an emotional encounter with his first crystal skull. He realized that crystal skulls form a link between the Earth and human consciousness. Since then he included crystal skulls in his studies, summarizing his ideas in a book "Crystal Skulls; Interacting with a Phenomenon," published in 2007. Currently his studies focus on the role of crystal skulls in the creation of energy fields, their role in the activation of Earth energies and their role in human spiritual evolution. He believes that both ancient and contemporary crystal skulls have a role to play.
