Is there simandar swami tirth
Yes.
In Jainism, Simandhar Swami is himself a living Tirthankara, currently residing in Mahavideh Kshetra (another region of the Jain universe). So:
- There is no Simandhar Swami Tirth on our Earth (Bharat Kshetra) in the sense of an actual place where he is physically present and preaching.
- On Earth, we only have temples / derasars with his idol, called Simandhar Swami Jinālaya / derasar / tirth, but these are symbolic places of worship, not the real Mahavideh Kshetra.
- According to Jain cosmology, his real tirth (samavasaran, deshna, sangh, etc.) is in Mahavideh Kshetra, where countless souls are presently listening to his preaching and progressing toward moksha.
Many Śvetāmbara Jains especially worship Simandhar Swami in temples, with the bhāv that:
- He is a currently living Tirthankara
- By remembering him and following Jain principles (ahimsa, satya, aparigraha, brahmacharya, tapas), we create causes to be born in Mahavideh Kshetra and one day actually reach his true tirth there.
