The four cosmic ages (Uga)

- The world moves through four Great Cycles birthing four Worlds: Uga Aka → Uga Chi → Uga Anwu → Uga Azi, succeeding one another through catastrophic, consciousness-expanding events. Cycles ascend (Uje Uga) and descend (Una Uga); a full cosmic cycle (Mgba Uga) = eight consciousness seasons, ending in a collective evolutionary leap (Opupu Mmuo/Ipu Mmuo).
- Uga Aka — age of non-duality, pure spirit/consciousness, omniscience, immortality.
- Uga Chi — age of duality's dawn: self-realized spirits, soul power, telepathy, ingenious cultural creation — and the first appearance of death (immortality lost). (Note: matches T1/Vol. 2's placement of death's origin in Uga Chi.)
- Uga Anwu — age of the Mind: solar-intuition visionaries (Umu Anwu), prophecy, technology, deep understanding of energy and consciousness, sudden worldwide ecological conscience. The present world is said to be emerging into an ascending Uga Anwu.
- Uga Azi — age of descent: pessimism, ignorance, destruction, greed; the world "upside down." (T1 also uses "this Azi generation" pejoratively for the present forgetful era.)

- These four world-seasons (Uga-Uwa-n'Ano) mirror the four market days Eke–Orie–Afo–Nkwo.
