Notes in Jain tradition

• During Chaturmās, sādhu‑sādhvijī generally stay in one place (sthiti) for svādhyāy, pratikramaṇ, and dīkshā‑anukūl sādhana; lay followers observe more saiyam, upavās/āyambil, and attend pravachans. This is common to both Digambar and Śvetāmbara paramparā.
• Mumbai civic practice this year recognizes key Paryushan days; local arrangements (e.g., cleanliness, quiet hours) are coordinated around these dates. For exact local timings, rely on your Colaba sangh notices. ( timesofindia.indiatimes.com )
