Nonduality is at the core of both transpersonal psychology and ecopsychology and provides a
means of finding common ground between these approaches. However, misunderstandings
and the lack of an adequate conceptual language for nonduality have limited the value
of this concept for ecopsychology. Nonduality is presented as a range of experiences and
stages of development in which particulars are perceived and understood as part of an allencompassing
totality. Specifically, nonduality is understood in terms of a self-identity
in which separating boundaries no longer isolate one from other expressions of Being. A
description of nondual dimensions of Being based on the Diamond Approach of A. H.
Almaas provides ways of articulating the transpersonal dimensions of ecopsychology
