Answer

Yes, devas may participate in dharma-related activities like listening to dharma, having reverence, doing prabhu darshan, and prabhu bhakti, but in Jain understanding this is generally not counted as tapas in the same way as for human beings.

Explanation

In Jain Dharma, tapas is mainly a discipline of self-restraint, purification, and karmic weakening.

• Swadhyay tap: studying, reflecting, and understanding dharma.
• Vinay tap: humility, reverence, and respectful conduct.

Devas can certainly have:

• dharma chintan,
• devotion,
• respect for the Tirthankar,
• participation in kalyanaks,
• janmabhishek,
• samavasaran seva/darshan.

But these are usually understood as devotional and meritorious acts, not the same kind of austerity practice that humans and monks undertake.

Spiritual Understanding

For devas, these activities arise because of their punya and their joyful devotion to the Tirthankar. For humans, swadhyay and vinay are part of sadhana that helps reduce ego and purify the soul.

So the key difference is:

• Devas: devotion and reverence
• Humans/munis: tapas as spiritual practice and inner purification

Takeaway

So the short answer is: devas may do acts of swadhyay-like reflection and vinay-like reverence, but not tapas in the same strict spiritual sense as human sadhana.
