Some alternative medicine practitioners who work with mental health have a somatic focus. For example, in somatic experiencing, clients learn to monitor internal sensations. Spiritual discourse within the field of somatics tends to reject monotheistic systems which locate spiritual authority in an external hierarchy, instead sacralizing the direct perception of an internal "life force". Although not strongly aligned with any particular spiritual tradition, somatics literature generally views Christianity and other monotheistic religions unfavorably and favors an eclectic mix of non-Western approaches to the sacred, including those of Buddhism, Taoism, Hinduism, and various kinds of Shamanism. Some spiritual practices, such as Sufi whirling and Buddhist walking meditation, are particularly associated with somatics. Spirituality is a component of the work of Bonnie Bainbridge Cohen, a leader in contemporary somatics who incorporates elements of Zen Buddhism with modern dance and Laban Movement Analysis.
