In Jain practice, a red string tied or kept after puja is generally seen as a symbol of auspiciousness, protection, and devotional remembrance. It is not the main focus of worship; the main purpose remains bhakti, purity, and inner reverence toward the Tirthankar.

In many Jain traditions, such sacred threads or strings may be used as:

• a sign of mangal (auspiciousness),
• a reminder of faith and discipline,
• or an item connected with a specific ritual or vow.

The exact meaning can differ by community and local tradition. In Jain Dharma, the true essence is always bhav-puja — pure intention, respect, and inner devotion.
