Here are the simplest, authentic ways to read the Kalpasutra:

• During Paryushan (Śvetāmbara tradition): Attend the daily vachan (public recitation) at your local derāsar/upāśraya. This is the most traditional way to hear it with proper reverence and context.
• Temple or community libraries: Most Śvetāmbara Jain temples keep printed Kalpasutra editions (original text with Gujarati/Hindi/English translations). Ask the librarian or the resident sādhus/sādhvīs for an approved edition.
• Authorized printed editions: Look for editions published by recognized Śvetāmbara Jain sanghs/trusts. They preserve the traditional text and its correct chheda-anuyoga context.
• For background before/alongside reading: See these brief explainers on Kalpasutra from JainKnowledge:

Notes on traditions:

• Śvetāmbara: Kalpasutra is canonical and publicly recited in Paryushan; personal reading should be done respectfully, preferably with guidance.
• Digambara: Kalpasutra is not a canonical text; Digambara followers generally study Tīrthankar-charitra through other revered works and focus during Daśa-lakṣaṇa on the ten supreme virtues.

Read with shraddhā, and if possible, under guidance of a learned monk/nun or a qualified pathak so the meaning (arth) is preserved correctly.
