In Jain cosmology, time is cyclical and divided into two halves: Utsarpini (ascending) and Avasarpini (descending). Kalyug (the Kali Yuga) is described as the later part of Avasarpini, a era in which dharma largely declines. Key Jain themes about Kalyug include:

• Dharma and ahimsa decline: Truth, non-violence, restraint, and ethical conduct become rarer; people are more greedy, deceitful, and prone to quarrel.
• Social and spiritual erosion: Quarrels, violence, and materialism increase; fewer people practice strict vows or renunciation.
• Lifespan and spiritual uplift: Life tends to shorten, and spiritual progress becomes harder for the average person, though rare souls may still achieve spiritual realization through disciplined practice.
• Hope within the cycle: Despite the decline, Jain teachings emphasize that liberation is always possible for individuals who sincerely follow the path of right conduct (samyak-darshan, samyak-jñana, samyak-chāra), and that enlightened beings (kevalins) and great monk-sages continue to appear at auspicious times.

Note on differences: Digambar and Shwetambar traditions may present minor variations in how they describe the exact sequence or emphasis within Kalyug, but both agree that this era is marked by a general decline in virtuous conduct.

If you’d like, I can point you to specific Jain scriptures or verses that discuss the time cycles and the nature of Kalyug in more detail.
