Sansar means the worldly realm or the cycle of worldly life (samsara), i.e., the world of birth, old age, disease, and death. Kal means time. Sansthan (sanstha) can be taken as establishment or arrangement/organization. So “sansar sansthan kaal” can be understood as the specific time or period when the worldly order or worldly existence is established or comes into being within the cosmic cycle.

In Jain thought, there is a strong emphasis on the cyclic nature of time (utsar and pralaya, i.e., rise and dissolution of cosmic orders) and on how souls wander through various states in samsara until they attain kevala jnana and liberation. The exact nuance of a phrase like sansar sansthan kaal can vary by text and tradition (Digambar vs. Shwetambar), and some sutras may phrase it in a way that highlights how the worldly world or its institutional order manifests in a particular era of the cosmic cycle.

If you can share the exact verse or a bit more context (which sutra chapter it’s from, or the surrounding lines), I can give you a precise, tradition-aligned arth (meaning) based on authentic Jain sources.
