In many Jain traditions, women are advised to pause certain religious practices during menstruation because this time is considered associated with bodily discharge, vulnerability, and possible impurity for ritual discipline.

From a Jain perspective, the usual reasons given are:

• Ahimsa: during periods, there may be more bodily secretions and involuntary movement, so some traditions prefer avoiding temple rituals to maintain the highest level of purity and non-violence.
• Shuddhi / ritual discipline: some practices, especially puja, temple entry, and touching idols, are traditionally done only in a state of bodily cleanliness.
• Traditional observance: this is a custom followed in many Jain families and temples, not the core teaching of Jain Dharma itself.

Important point:

• This does not mean women are spiritually less capable.
• Women can still pray, do samayik, read scriptures, do pratikraman mentally, and remember the Tirthankars with devotion, depending on family and community tradition.
• Practices can vary between Digambar and Shwetambar communities and even from temple to temple.

So, in Jainism, the restriction is usually about ritual purity and non-violence discipline, not about disrespect toward women.

If you want, I can also explain the Jain scriptural and traditional basis for this in simple language.
