Answer

In Jain Dharma, during Paryushan, the focus should remain on:

• Arihant Bhagwan
• Siddha Bhagwan
• Acharya, Upadhyay, and Sadhu-Sadhvi Bhagwant
• Self-purification, pratikraman, tapasya, forgiveness, and samayik

So, from a Jain spiritual viewpoint, it is generally not considered appropriate to perform Ganpati aarti as a religious practice during Paryushan, even if Ganpati is considered only as a dev and not supreme.

Explanation

Jain Dharma does acknowledge the existence of devas and devis, but they are also worldly beings within samsar. They are not liberated souls.

In Jain worship, the highest reverence is given to those who have conquered attachment and aversion:

• Arihants — living omniscient beings
• Siddhas — liberated souls

Paryushan is a sacred time especially meant for turning inward, reducing worldly activities, and strengthening Jain practices. Therefore, devotional practices during Paryushan should ideally be aligned with Jain principles.

Spiritual Understanding

Even if one respects Ganpati as a dev, Jain Dharma teaches that devas are not the ultimate refuge for liberation. Liberation comes through:

• Samyak Darshan
• Samyak Gyan
• Samyak Charitra
• Ahimsa
• Tapasya
• Detachment

During Paryushan, the mind should be directed toward atma-shuddhi — purification of the soul — rather than worship of worldly deities.

Takeaway

Respecting Ganpati as a dev is one thing, but performing Ganpati aarti during Paryushan is not part of Jain religious practice. A Jain should preferably devote Paryushan to Navkar Mantra, Pratikraman, Samayik, Swadhyay, Tapasya, and worship of Arihant-Siddha Bhagwan.
