Answer

Yes, you may use the same pooja clothes again for pooja, as long as they remain clean and not soiled.

Offering chapati to a cow is considered a compassionate and good act. Simply feeding a cow does not make your pooja clothes impure.

Explanation

In Jain Dharma, cleanliness for pooja is important because pooja is done with respect, discipline, and inner purity.

You should check:

• If the clothes touched cow saliva, dirt, urine, dung, or became visibly dirty, then wash them before using again for pooja.
• If the clothes remained clean, you can wear them again for pooja.
• If you feel doubt in your mind, it is better to wash them for peace and purity of bhav.

Spiritual Understanding

Jain Dharma gives importance to both:

• External cleanliness — clean body and clean clothes for worship.
• Internal purity — humility, compassion, non-violence, and devotion.

Feeding a cow with kindness is not spiritually wrong. Just maintain cleanliness before doing pooja.

Takeaway

If your pooja clothes are clean, you can use them again. If they became dirty or touched cow saliva/dung/urine, wash them before pooja.
