The staged vocabulary, bionation, psychonation, and beyond, appears in Kushi's later lectures and One Peaceful World-era writings (1980s), describing humanity's passage from a biological stage (bionation) through a psychic integration stage (psychonation) toward a fully realized 'ultra-psychonation'. The scheme extends Ohsawa's seven stages of judgment and his biological-evolution claims; the texts are lectures and popular books, not peer-reviewed biology, and the archive labels them accordingly.
New Age futurism absorbed the ladder as one more ascension timetable, the same shape as every other schedule of human transformation: a date, a stage name, a dietary or spiritual prerequisite. It sits in a documented genre, from Teilhard de Chardin's Omega Point (The Phenomenon of Man, 1955) to New Age 2012ism.
The ladder's hidden premise is Lamarckian mysticism: what you eat rewrites what you are, and populations eating in alignment rewrite humanity itself. Read as metaphor it is about discipline; read as mechanism it has no evidence; either way it is one of the few diet systems that claims to be a species transition protocol.
If evolution can be steered by diet, who writes the menu?
