Answer

In Jain tradition, if a girl notices even one spot of menstrual blood, it is generally treated as the beginning of menstruation. So she should avoid visiting Derasar until the menstrual period is completed and she has taken proper bath/purification according to her family and sampradāy practice.

Explanation

Even if there is no continuous bleeding, a blood spot may indicate that the menstrual cycle has started. Because Derasar is a place of worship with strict purity practices, traditional Jain conduct advises extra caution.

She may still do bhāv-pūjā from home, such as:

• Namokar Mantra
• Pratikraman or simple repentance
• Darshan-bhāv mentally
• Reading or listening to Jain teachings

Spiritual Understanding

Not going to Derasar during menstruation is not considered a lack of devotion. In Jain Dharma, inner purity, humility, and respect for temple maryādā are very important.

Takeaway

If it was a menstrual blood spot, she should not visit Derasar at that time. If there is doubt, it is best to follow the stricter path and consult a trusted Jain elder, guru, or temple authority.
