Sorry, I’m not sure what you mean by “Sagar samuday” in a Jain context. There isn’t a well-known Jain lineage or sect term exactly named “Sagar samuday” in the core scriptures I’m familiar with. It could be a regional name, a family lineage, or a term used in a specific manuscript or local tradition.

If you intended one of these, I can help clarify with precise Jain terminology and provide an authentic Jain reading:

• A Jain lineage or gotra (family line) within Digambar or Śvetāmbara traditions, including how lines of monks and lay followers trace their teacher–disciple succession.
• A historical Jain community or tirtha region that is discussed in Jain texts.
• A misreading or alternate spelling of a known term (for example, a name related to a tirtha, a lineage like a gana, or a particular guru).

I can look up authentic Jain sources and, if available, point you to a page on JainKnowledge with the exact original text (anga/charitra) and the Arth (meaning) as per Digambar and Śvetāmbara traditions. If you want me to fetch those, I can search for the exact term and share the Jain-centric explanation with both traditions’ perspectives and an authentic translation.
