Despite its highly eclectic nature, a number of beliefs commonly found within the New Age have been identified. Theologically, the New Age typically adopts a belief in a holistic form of divinity that imbues all of the universe, including human beings themselves. There is thus a strong emphasis on the spiritual authority of the self. This is accompanied by a common belief in a wide variety of semi-divine non-human entities, such as angels and masters, with whom humans can communicate, particularly through the form of channeling. Typically viewing human history as being divided into a series of distinct ages, a common New Age belief is that whereas once humanity lived in an age of great technological advancement and spiritual wisdom, it has entered a period of spiritual degeneracy, which will be remedied through the establishment of a coming Age of Aquarius, from which the milieu gets its name. There is also a strong focus on healing, particularly using forms of alternative medicine, and an emphasis on the notion that spirituality and science can be unified.
