Clear answer: In Jain dharma, this is generally not condemned outright if it is done to reduce suffering and is medically needed, but it is not considered a spiritual solution for the soul.

Jainism teaches that the soul is separate from the body. So the true path is not to change the body to change the soul, but to reduce attachment, delusion, and inner suffering through right conduct, self-restraint, and non-violence.

So the practical Jain view is:

• If the surgery is to lessen suffering and helps the person live more peacefully, it can be acceptable as a worldly/medical decision.
• If it is seen as a way to “fix” the soul-body relation, Jainism would not support that idea.
• Any medical action should be judged by ahimsa, minimum harm, and sincere intention.

So the simplest Jain answer is: acceptable as a compassionate medical choice, but not as a spiritual necessity or cure for the soul.
