Answer

In Jain Dharma, a monk should handle this with ahimsa, restraint, and guidance from the guru or acharya.

If a tapeworm is inside the body, the monk should generally:

• Inform the spiritual teacher or senior monk
• Take the least harmful treatment possible
• Avoid any unnecessary violence
• Maintain calmness and detachment
• Act with the intention of preserving the body for spiritual practice, not for attachment

Explanation

Jain ethics do not support causing harm unnecessarily. At the same time, the body is the instrument for sadhana, so if a parasite is causing illness, treatment may be accepted when needed, as long as it is done with the minimum possible violence.

In Jain thought:

• Intention matters
• Unavoidable harm is different from deliberate harm
• The least हिंसा is preferred
• Proper guidance is important in monastic life

Spiritual Understanding

A Jain monk’s goal is to protect dharma, discipline, and inner purity. So the right approach is not panic, and not negligence, but:

• Equanimity
• Non-attachment
• Careful, minimal-harm action
• Respect for both life and monastic vows

Takeaway

A Jain monk should seek guidance and choose the most non-violent necessary treatment, while remaining शांत, संयमी, and detached.
