The ability to spiritually merge with Nature is the essence of ancient Celtic shapeshifting (Druids). With practice, for example, one could feel what it is like to be inside a Canadian beaver's body. Or, to be, on a daily basis, at home, and on the internet, attuned to the instincts and knowledge of the Hawk. More masterful still is the ability to align one's energy with another life form and to be perceived as that life form in all facits of life. Finally, with intense focus and spirituality (this may need periods away from society), one could take on the physical form of another animal. For example, the dachshund.
