Yes, in Jain Dharma the pain you experience is still the result of karma—more precisely, it is the fruition of previously bound karma. Even if you choose an action like surgery, the body may then experience pain, but the capacity to feel that pain is understood in Jainism as due to karmic unfolding.

At the same time, choosing surgery does not mean you “created” the pain in the same spiritual sense. The physical event is a condition, but the underlying experience of suffering is linked to karma already bound.

And yes — tolerating that pain with equanimity is spiritually beneficial. In Jainism, when pain arises and one remains:

• calm,
• non-attached,
• without anger, complaint, or fear,
• and with awareness of the soul’s distinct nature,

then that becomes samyak bhāva and helps in stopping new bondage and weakening old karmas. Enduring pain with inner balance is considered a form of spiritual strength.

So the Jain understanding is:

• Pain is karmic fruition.
• The decision to undergo surgery is a conscious action.
• Facing the pain with equanimity is spiritually पुण्य/beneficial in the sense of purification and progress.

In simple words: Yes, the pain is still karmic, and yes, bearing it with equanimity supports spiritual development.
