In Jain Dharma, three different points are important here:

1. What is called “impure” (ashaucha)?

- Jainism never says that a woman herself becomes bad, low, or sinful because of periods. - “Ashaucha” here means ritual non‑fitness for certain temple activities for some time, not moral or spiritual impurity. - The soul (jīva) is always pure. The rules are about external cleanliness when doing very high‑shuddhi acts like abhishek, dravya‑pūjā, touching idols and scriptures. ( jainknowledge.com)

1. Why only 3 days, when bleeding may last 6–7 days?

- Jain scriptures do not fix “exact 3 days”; this is mostly community / family maryādā (custom). - In many Jain homes it is: - Avoid temple/dravya‑pūjā for 3 days, - On the 4th day: full bath with head wash and clean clothes, then again start normal mandir‑pūjā. ( jainknowledge.com) - Other families may follow 4 or 5 days. - So 3 days is not a hard Jain āgamic rule, it is a minimum, practical standard that became common: - First 2–3 days: generally more flow, more weakness – so tradition says: “Rest more, avoid heavy ritual work.” - After that, if bleeding is light and the woman has done proper snān and changed everything, many achar‑maryādās allow her back to normal ritual work, even if a little spotting continues. - In short: count of days = custom, not a statement that later blood is “pure” or “hygienic.” It is only a practical boundary for ritual life.

1. Is the remaining bleeding unhygienic or ignored?

- Jain view is very consistent: all body discharges – blood, urine, feces, semen, phlegm, etc. – are treated as ashuddhi for rituals because they contain countless micro‑organisms and are naturally unclean. ( jainknowledge.com) - So it is not only about women. A man with a nosebleed, pus, or other discharge is also expected to clean fully and avoid touching murtis or scriptures until proper shuddhi is restored. ( jainknowledge.com) - During any days of flow, Jain Dharma expects: - good personal hygiene, - clean undergarments and pads, - separate āsan for sādhanā, - avoiding soiling of puja‑upkārans, murtis, granths. ( jainknowledge.com) - So the bleeding itself is always treated as something to be handled very cleanly; it is never considered “hygienic”. - The 3‑day (or 4/5‑day) rule only fixes when full dravya‑pūjā etc. may resume, provided proper bath and cleanliness are done.

Digambar and Śvetāmbara differences (short)

• Both:

- See menstruation as a time to pause temple/dravya‑pūjā and keep extra shuddhi. ( jainknowledge.com)

• Digambar (generally stricter):

- More emphasis on not entering garbhagṛha or touching murtis/pujā items during periods. ( jainknowledge.com)

• Śvetāmbara:

- Often allow darshan from outside the sanctum and inner bhāva‑pūjā; details vary by sangh and local rules. ( jainknowledge.com)

Spiritual point to remember

• Menstruation is a natural process, not a sin.
• What is restricted is some external rituals, for a limited time, to maintain high ritual cleanliness and reduce possible himsā to minute beings.
• Inner sādhanā — Navkār mantra, samayik, pratikraman (done appropriately), japa, swādhyāy by listening, good thoughts — can continue throughout. ( jainknowledge.com)
