Yes, Jain scriptures mention the concept of Utsarpini. Utsarpini is a Jain cosmological term describing the ascending half of the time cycle, during which conditions in the world gradually improve. Its counterpart is Avasarpini, the descending half, when conditions worsen.

References to Utsarpini and Avasarpini are found in several Jain texts, particularly in the Śvetāmbara and Digambara traditions. Important scriptures that discuss these time cycles include:

1. Tattvartha Sutra (also called Tattvarthadhigama Sutra) – This foundational Jain text by Acharya Umasvati describes the time cycles (kālachakra) and the concepts of Utsarpini and Avasarpini in detail (see Tattvartha Sutra, Chapter 5).
2. Tiloyapannatti – An ancient Prakrit text which elaborates on Jain cosmology and the cycles of time.
3. Trilokasara by Acharya Nemichandra – Explains cosmological concepts including Utsarpini and Avasarpini.
4. Gommatsara by Acharya Nemichandra – Also discusses the division of time and the characteristics of each era.

These texts explain how Utsarpini consists of six “aras” (periods), each with its own distinct characteristics, and how the spiritual and material conditions of living beings change during these periods.

If you are looking for scriptural verses or stories specifically about Utsarpini, you will find them in the chapters dealing with kālachakra (the wheel of time) in the above-mentioned texts. Most Jain cosmological charts and commentaries also include detailed descriptions of Utsarpini and Avasarpini.
