Answer

In Jain practice, if the cotton rui for a divo has been touched by a person during the third day of periods, it is generally better not to use that cotton for pooja.

Use fresh cotton rui instead, especially for temple worship, dev-puja, or any formal religious ritual.

Explanation

Many traditional Jain households observe rules of ritual purity during menstruation. During those days, a person usually avoids:

• Touching pooja items
• Preparing items for pooja
• Touching idols, scriptures, or temple objects
• Participating in formal pooja rituals

So if the rui was touched during that time, the safest and most respectful approach is to keep it aside for ordinary use and take fresh cotton for the divo.

Spiritual Understanding

This is not about disrespecting the person. In Jain Dharma, such rules are followed mainly for maintaining traditional ritual discipline and purity in worship.

The person herself is not spiritually impure. The restriction is connected to religious conduct and ritual maryada followed in many Jain families.

Takeaway

For pooja, use fresh untouched cotton rui. The previously touched cotton can be used for non-pooja purposes.
