In Samayasār, Avishesh means without distinction, undifferentiated, or non-divided.

In the Jain philosophical context, it points to the pure soul (jīva) being understood in its essential nature, beyond all outer differences such as:

• body
• gender
• name
• caste
• form
• worldly conditions
• karmic coverings

So, Avishesh refers to the abheda, nirvikalp, shuddha svarūp of the soul — the आत्मा as one pure conscious substance, not as seen through worldly distinctions.

In simple words:

• Saviśesh = with distinctions, qualities, or differences
• Avishesh = without distinctions, in pure essential nature

In Samayasār, this idea is used to help the seeker turn attention from the relative/worldly viewpoint to the real/substantial viewpoint, where the soul is known as pure knower and seer.

If you want, I can also explain Avishesh in the specific Gatha context of Samaysar in simple arth.
