• Deravasi (also Murtipujaka or Mandir-margi) and Sthanakvasi are two Śvetāmbara Jain groups. The main difference is how they worship: Deravasi accept temple worship and idols, while Sthanakvasi reject idol worship and worship in simple prayer halls without images. This distinction is often summed up as temple/ idol worship versus non‑image worship. ( jainknowledge.com)

• Origin and focus:

- Deravasi emerged from the traditional Śvetāmbara path that continues temple-based rituals and image veneration (mūrti-pūjā) in derasars/temples. They see idol worship as a valid aid to devotion and concentration. ( jainpedia.org) - Sthanakvasi arose as a reform within Śvetāmbara Jainism, emphasizing inner worship, ethical discipline, scriptural study, and meditation in places called sthanakas—without idols or temple rituals. They are sometimes described as “hall‑dwellers” (sthāna = place, kāsīna = hall) and stress bhāva‑pūjā (inner devotion) over external rites. ( jainpedia.org)

• Practical differences you might notice:

- Place of worship: - Deravasi: temples/derāsār with images of Tirthankaras. - Sthanakvasi: no temples with idols; gatherings in sthanakas (prayer halls). - Worship style: - Deravasi: dravya‑pūjā (offerings, rituals) and ritual ceremonies in front of murtis. - Sthanakvasi: bhāva‑pūjā (internal devotion), pratikramaṇ, sāmayik, svādhyāy; no idol rituals. - Monastic observances (mukhapattī, the mouth cloth): - Sthanakvasi typically wear a mūkhapatṭī (cloth over the mouth) at all times; Deravasi generally do not, though practices can vary among groups. ( jainknowledge.com) - Scriptures and tradition: - Both share Śvetāmbara beliefs, but Sthanakvasi historically recognize a different, narrower set of scriptures and emphasize their own ritual practices.

• What remains the same:

- Both belong to Śvetāmbara Jainism and share core beliefs: the 24 Tirthankaras, karma and mokṣa, non‑violence, and the general Jain path. The difference is essentially “how to worship,” not a different fundamental creed. ( jainpedia.org)
