Answer

In Jain Dharma, eternal temples usually means shashwat temples or shashwat tirthas—sacred places of worship that are regarded as timeless, ancient, and not created in one historical moment.

Explanation

These are believed to be holy Jain temples or pilgrimage places that:

• are eternal in nature according to Jain tradition,
• are not ordinary man-made temples in the usual sense,
• are associated with Tirthankars, divine worship, and spiritual merit,
• are considered part of the cosmic and spiritual order.

In simple words, they are seen as permanent sacred abodes of devotion, unlike regular temples that are built, repaired, and eventually may decay.

Spiritual Understanding

The idea of eternal temples teaches that:

• dharma is timeless
• devotion to the Jinas is not limited by one era
• sacredness is not only in stone buildings, but in the pure spiritual presence connected with the Tirthankars

For Jain devotees, these places inspire:

• reverence
• self-purification
• non-attachment
• faith in the eternal truth of Jain Dharma

Takeaway

So, eternal temples in Jainism are sacred, timeless pilgrimage places considered everlasting in tradition. They symbolize the permanent and pure nature of Jain spiritual truth.
