This book presents rich source material; it makes no claim to being
academic, though referring whenever possible to works available to the
authors (the bibliography more or less stops with Ian Gordon-Brown's
death in 1996). However, those interested in Transpersonal Psychology as
an academic discipline will be able to avail themselves of the wealth of
original material here and take it into the world of comparative study.
Its origins could be traced back way beyond Jung, Frankl, Maslow and
Assagioli to Far Eastern and Aboriginal sources, to Greek and later
Western teaching, to other great transpersonal pioneers of the twentieth
century and forward into the twenty-first.
