Here is a simple Jain-centered view of the two groups you asked about.

• 22-Panthi Sthanakvasi (Svetambara) aka Baistola/Baisampradya

- Identity: A Svetambara Sthanakvasi sub-sect that organizes itself into a network of many panths (often described as 22 in some traditional accounts). Like other Sthanakwasi groups, they emphasize non-idol worship and practice in sthanakas (prayer halls) instead of temples. They maintain a more decentralized leadership structure with multiple teachers/acharyas over time. They are part of the non-idolatrous strand of Svetambara Jainism. You can read about Sthanakwasi characteristics and their general stance here. - Practice and emphasis: Focus on meditation, scriptural study, and ethical living in simple communal settings rather than temple rituals. They typically accept a subset of Svetambara scriptures (historically about 31–32 texts) and avoid idol worship. The approach is broader in organizational diversity compared to Terapanthi. See related notes on Sthanakwasi practices.

• 13-Panth Terapanthi (Śvetāmbara Terapanthi)

- Identity: A distinctive offshoot of the Svetambara tradition founded by Bhikshu in the 18th century (1760 CE). It is known for its relatively centralized leadership under a single Acharya and a codified set of ethical principles (often described as the 13 “terapanth” guidelines: the 5 Mahavratas, 5 Samitis, and 3 Guptis). It is non-idolatrous and temple-free, but unlike some Sthanakwasi groups, it has a more formal organizational structure. You can read a concise comparison and Terapanthi basics here. - Practice and emphasis: Emphasizes disciplined monastic life, group prayers, scriptural study, and a strong central guidance under the Acharya. Like Sthanakwasi, it rejects idol worship and temple-centered worship, but it is more centralized in governance and slightly stricter in certain disciplines. See detailed notes on Terapanthi practices and leadership.

Key points to remember

• Both are Śvetāmbara Jain groups that reject idol worship and temple-centric rituals.
• The Sthanakwasi tradition (including Baistola/22-panthi variants) tends to be more decentralized and historically broader in textual reception, with multiple teachers and somewhat flexible practices.
• The Terapanthi tradition is a more centralized offshoot with a formal 13-principle framework and a single Acharya as spiritual head.
• Both are non-idolatrous within the Śvetāmbara fold, but their organizational structures and historical development differ as described above.

If you’d like, I can point to more specific JainKnowledge pages that detail the 13-principle Terapanthi framework or the textual canons recognized by Sthanakwasi groups.
