"Sushama sushama" is not a standard, well-attested mantra or phrase found in Jain scriptures that are typically associated with the avasarpini (the descending half of the cosmic time cycle). In Jain cosmology, avasarpini refers to a long period that begins after the dissolution of the previous cycle and runs through many ages of Jinas, Tirthankaras, and worldly beings. Digambaras and Shwetambaras both describe its phases, but there is no canonical record of a phrase like “Sushama sushama” tied specifically to avasarpini.

If you have a particular text or citation in mind (even a little context like the language, a paragraph, or the source you saw it in), I can help explain that passage precisely and translate or interpret it according to Jain tradition.
