The 'Uttama Bhogbhumi' (Supreme Land of Enjoyment). The earth is sweet as sugar, devoid of dust or thorns. There is no agriculture or trade; 10 types of Kalpavrikshas (Wish-Fulfilling Trees) like 'Madyanga' (Wine) and 'Jyotiranga' (Light) provide everything. Humans are born as Yugaliks (Twins), live as spouses, and die together peacefully. Digestion is 100% efficient (no excreta). They feel hunger only once every 3 days and eat a morsel the size of a jujube fruit.

The 'Madhyama Bhogbhumi' (Intermediate Land of Enjoyment). The pristine energy begins to fade. The light of the Kalpavrikshas dims slightly, and the sun/moon become more visible. Humans now feel the urge to eat every 2 days instead of 3. The rib count drops to 128, indicating a reduction in physical solidity, but life remains anarchic, peaceful, and devoid of 'mine vs thine' concepts.

The Transition Era. The Kalpavrikshas fail and vanish, causing panic. The 14 Kulakaras (Manus) appear to guide humanity. They invent the 3 Punishments: 'Hakkara' (Alas!), 'Makkara' (Do not!), and 'Dhikkar' (Fie!). Due to the 'Hunda Avasarpini' anomaly, the lifespan ends at 84 Lakh Purva instead of 1 Crore Purva. Rishabhdev (1st Tirthankara) is born and teaches the 6 Professions (Asi, Masi, Krishi, etc.) as nature stops providing.

The 'Karmabhumi' (Land of Action). This era hosts the 63 Salakapurusas (24 Tirthankaras, 12 Chakravartins, etc.). Religion is fully established, and Moksha is attainable. However, physical decline is catastrophic: heights drop from 3000 ft (Rishabhdev) to 10.5 ft (Mahavira). This era is marked by anomalies like the Mahabharata/Ramayana wars and the early death of Tirthankaras relative to the standard cycle.

Current Era (Pancham Kaal). No Tirthankaras present. Human bones lack the 'Vajrarishabhanaraca' structure required for Shukla Dhyana, making Moksha physically impossible from Bharat Kshetra. The era will end with the death of the last 4 practitioners: Muni Virangada, Aaryika Sarvasri, Shravak Agnila, and Shravika Pangushri. Upon their death, the element of Fire will vanish from earth.

The Age of Barbarism. Civilization collapses completely. Humans shrink to dwarf-like beings (1-1.5 ft), live in 72 types of 'Bils' (caves) near rivers like Ganga, and eat raw meat/fish as fire is lost. There is no family, marriage, or government. The era ends with 49 days of 'Samvartaka' rains (Acid, Poison, Fire, Stone) that destroy all life, except a few protected seeds in caves.
