Yes — almost every major religious or mythic tradition has some analogue to the Kali Yuga: a late, degenerate, or “end-times” phase in a cosmic cycle when morality decays, social order collapses, and spiritual connection weakens. While the cultural specifics differ, the pattern is strikingly consistent: a movement from a “golden” or ordered beginning toward a chaotic, spiritually impoverished end, often followed by renewal.

Here’s a comparative outline:

---

1. Hinduism — Kali Yuga

• Source: Purāṇas, Mahābhārata, Manusmṛti

• Nature: The last of the four yugas (Satya, Treta, Dvāpara, Kali), marked by moral decline, hypocrisy, materialism, and loss of dharma.

• Duration: 432,000 years, with us said to be a few thousand years in.

• End: Vishnu’s avatāra Kalki will appear to restore dharma and start a new Satya Yuga.

---

2. Ancient Greece & Rome — Iron Age (Hesiod & Ovid)

• Source: Hesiod’s Works and Days, Ovid’s Metamorphoses.

• Nature: After the Golden, Silver, and Bronze Ages, humanity declines into the Iron Age — marked by injustice, greed, and violence.

• End: Not always cyclical in Greek thought — in some versions, decline is linear, leading to an eventual divine judgment or destruction.

---

3. Norse Mythology — Ragnarök

• Source: Poetic Edda, Prose Edda.

• Nature: Preceded by Fimbulwinter (three years of winter, chaos, and betrayal), moral order collapses, kin slays kin, and the gods themselves die.

• End: The cosmos is destroyed but then renewed — green earth rises again, surviving gods and humans repopulate it.

---

4. Zoroastrianism — End of the Fourth Age

• Source: Avesta, Pahlavi texts (Bundahishn).

• Nature: Time is divided into four ages of 3,000 years each. In the final age, evil’s influence peaks, moral decay spreads, and society becomes corrupt.

• End: The Saoshyant (savior) arrives; Ahura Mazda defeats Angra Mainyu, resurrects the dead, and renews creation.

---

5. Abrahamic Traditions — End Times / Latter Days

• Christianity:

  • The “Last Days” before Christ’s Second Coming involve apostasy, moral collapse, and lawlessness (cf. 2 Timothy 3, Matthew 24, Revelation).

  • Tribulations, Antichrist, cosmic upheaval precede divine renewal — a New Heaven and New Earth.

• Islam:

  • The Akhir al-Zaman (“End of Time”) is marked by the loss of faith, rampant injustice, and moral corruption.

  • The Mahdi and Jesus return to defeat the forces of evil before the Day of Judgment.

• Judaism:

  • The Chevlei Mashiach (“birth pangs of the Messiah”) bring suffering and moral decay before the Messianic Age.

---

6. Buddhism — The Dharma Decline (Mappō, Mo-fa)

• Source: Mahāyāna sūtras (e.g., Lotus Sūtra).

• Nature: After the Buddha’s passing, the Dharma passes through True, Semblance, and Degenerate phases. In the final age, people are unable to follow the teachings, corruption spreads even in the sangha, and social disorder prevails.

• East Asia:

  • Japan’s Mappō era concept was popular in medieval times — seen as an age when only faith in Amida Buddha could save beings.

---

7. Indigenous & Mesoamerican Cycles

• Aztec: The Fifth Sun is the current age, preceded by four destroyed worlds. This age is prophesied to end in earthquakes after human hubris and imbalance.

• Maya: The Long Count calendar describes great cycles ending in cosmic resets; end of a baktun is not necessarily apocalyptic, but can mark profound shifts.

---

8. Chinese Dynastic & Cosmic Cycles

• Mandate of Heaven: When rulers become corrupt and society degenerates, Heaven withdraws its mandate, leading to collapse and renewal.

• Five Phases (Wu Xing) cycles: Although more about elemental transformation, late-phase disorder is often linked to moral decline in Confucian thought.

---

Common Threads Across Traditions

• Moral and spiritual decay before renewal.

• Breakdown of social order and loss of just leadership.

• Cosmic or divine intervention to restore balance.

• Cyclical or teleological time — either a recurring pattern (Hinduism, Buddhism, Norse myth) or a linear path to final resolution (Abrahamic faiths).

• Human culpability — decline often attributed to greed, ego, and neglect of the sacred.

If you want, I could map these into a side-by-side table showing how each tradition conceptualizes the start, decay, crisis, and renewal — so you can see exactly where Kali Yuga lines up with Iron Age, Mappō, Ragnarök, etc. That would make the parallels clearer than narrative form.

When is each said to occur?

ChatGPT said:

Alright — here’s a timeline-style breakdown of when each “Kali Yuga–like” period is said to occur in its own tradition, and whether it’s considered past, present, or future from the perspective of believers.

---

1. Hinduism — Kali Yuga

• When: Began traditionally in 3102 BCE, shortly after Krishna’s departure from the world.

• Now?: Yes — we are currently in it. It is to last 432,000 years, so only ~5,127 years have passed.

• End: Kalki avatāra appears, destroys adharma, and ushers in a new Satya Yuga.

---

2. Ancient Greece & Rome — Iron Age

• When: For Hesiod (8th–7th century BCE), the Iron Age had already begun in his time.

• Now?: For the ancients, yes; for us, the schema isn’t actively “lived” as prophecy.

• End: Not cyclical in mainstream classical thought; some later Stoic and Platonic traditions imagined renewal through ekpyrosis (cosmic conflagration).

---

3. Norse Mythology — Ragnarök

• When: A future event, preceded by moral collapse and Fimbulwinter.

• Now?: Not yet — but in some modern readings, signs (wars, climate events, kin-slaying) are “prefigurations.”

• End: The death of gods and destruction of the world; then rebirth of the cosmos.

---

4. Zoroastrianism — End of the Fourth Age

• When: History divided into 4 × 3,000-year epochs. We are in the final 3,000-year age, which began with Zoroaster (anywhere from 6th millennium to 6th century BCE depending on tradition).

• Now?: Yes — currently in the late stage of the last age, when evil’s influence peaks.

• End: Arrival of the Saoshyant, final defeat of evil, resurrection, renewal.

---

5. Abrahamic Traditions

• Christianity (Last Days):

  • When: In the New Testament, the “last days” begin with Christ’s resurrection. Many Christians believe we are in them now, awaiting intensified tribulations.

  • Now?: Yes, but interpretations vary — some see it as ongoing since the 1st century CE, others as entirely future.

• Islam (Akhir al-Zaman):

  • When: Preceded by moral decay, injustice, and specific portents (e.g., Dajjal, return of Isa). No fixed date.

  • Now?: Many Muslim scholars historically saw their own time as entering these phases; others place it in the near or distant future.

• Judaism (Chevlei Mashiach):

  • When: No fixed time; often imagined as imminent when conditions are dire.

  • Now?: Depends on interpretive tradition; some Hasidic and mystical circles say we are in it.

---

6. Buddhism — Mappō / Mo-fa (Degenerate Age)

• When: Three periods after the Buddha’s death:

  1. True Dharma (~500 years)

  2. Semblance Dharma (~500–1,000 years)

  3. Degenerate Dharma (Mappō) lasting 10,000 years.

• East Asia:

  • In Japan, Mappō was believed to have started in 1052 CE.

  • In China, similar concepts (Mo-fa) date degeneration to centuries after the Buddha’s parinirvāṇa.

• Now?: Yes — in East Asian reckoning, we’ve been in it for almost a millennium.

---

7. Aztec & Maya

• Aztec — Fifth Sun:

  • When: We are currently in the Fifth Sun. The end date was not fixed but was expected after a period of imbalance and catastrophe (especially earthquakes).

  • Now?: Yes — they saw their own era as fragile and temporary.

• Maya — Long Count Cycle:

  • When: Cycles of 5,125 years; the last cycle began in 3114 BCE and “ended” in 2012 CE. Not necessarily destructive — more a transition point.

  • Now?: In a new baktun; what happens is interpretive.

---

8. Chinese Dynastic & Cosmic Cycles

• Mandate of Heaven loss:

  • When: Happens whenever rulers are corrupt, natural disasters strike, and social order breaks down — no fixed schedule.

  • Now?: Cyclical, tied to political events; Qing dynasty fall in 1912 was seen as such a loss.

• Wu Xing cycles:

  • When: Transformation from one element’s dominance to another can accompany crisis and renewal — not rigidly dated.

If you like, I can map all these onto a single comparative “cosmic clock” diagram showing where each tradition thinks we are in its own degeneracy cycle. That would make the overlaps and divergences visually obvious.
