Residence in Jain cosmology.
"Tirthankara" Simandhar Swami resides at "Mahavideh Kshetra", another land within the Jain cosmological universe (see Jain cosmology).
The five lands of the Bharat Kshetra are currently in the 5th Ara (a degraded time-cycle in which Tirthankaras do not take birth). The most recent "Tirthankara" present on "Bharat Kshetra" (present world) was Vardhamana Mahavira, whom historians estimate lived between 599-527 BCE, the last in a cycle of 24 Tirthankaras.
On Mahavideh Kshetra, the 4th Ara (a spiritually elevated time-cycle) exists continuously. There, Tirthankaras perpetually are born. There are 5 Mahavideh Kshetras, each being a separate land. At present, there are 4 Tirthankars residing in each Mahavideh Kshetra. Thus there are a total of 20 Tirthankaras residing there, Simandhar Swami being one among them.
