In Jainism, the concept of a Tirthankar is very specific. Tirthankars are spiritual teachers who have attained perfect knowledge (Kevala Jnana) and establish the fourfold order (sangha) of monks, nuns, laymen, and laywomen. According to Jain scriptures, there are 24 Tirthankars in each half-cycle of time (Avasarpini and Utsarpini) in the present era, and their names and life stories are already determined and described in the Jain texts.

A "goshala" is a shelter or sanctuary for cows and is considered a meritorious institution in Jainism due to the principle of ahimsa (non-violence). However, a goshala is not a being and therefore cannot become a Tirthankar or Sarvagna (omniscient being).

Regarding "sarvagna," in Jainism, this refers to a soul that has attained Kevala Jnana—omniscience. Only individual souls (jivas) can become Sarvagna, not institutions or places.

So, according to Jain philosophy and scriptures:

• A goshala cannot become a Tirthankar or Sarvagna in the future because only souls (not places or institutions) can attain these states.
• The list of Tirthankars is fixed in Jain cosmology.

If you are referring to the possibility of a soul (perhaps one involved in managing or serving in a goshala) attaining such states, Jainism teaches that any soul, through right faith, knowledge, and conduct, can eventually attain liberation (moksha), and potentially, in the appropriate cosmic era, become a Tirthankar or Sarvagna. However, the goshala itself, as a non-living institution, cannot.
