In Grof's most recent work he moves the perinatal theory in a new direction. The specifics of biological birth as well as any subsequent experiences of spiritual death and rebirth are determined by four archetypes, one for each matrix. Grof (2000) writes that he felt compelled to change his early concept as a result of
Richard Tarnas’ realization that my description of the phenomenology of the four basic perinatal matrices (BPMs), experiential patterns associated with the stages of biological birth, showed astonishing similarity to the four archetypes that astrologers have empirically correlated with the four outer planets of the solar system. My description of the BPMs was based on clinical observations made quite independently many years before I knew anything about astrology, (p. 10-11)
Grof and Tarnas (2004) have combined archetypal psychology with astrology and changed the backbone of Grof's theory. Currently, Grof sees each matrix as ruled by a particular archetype. BPM I is governed by Poseidon, BPM II by Cronos, BPM III by Hades, and BPM IV by Prometheus. These archetypes will be described in more detail in sections that follow.
