I can help, but please tell me which Jain practice, belief, ritual, or concept you want the scientific reason for.

For example:

• Why Jains avoid eating after sunset?
• Why Jains do fasting?
• Why Jains avoid root vegetables?
• Why Jains drink boiled water?
• Why Jains do Pratikraman?
• Why Jains practice Ahimsa?
• Why Jains avoid green vegetables during Paryushan?

Once you specify “this,” I’ll explain it respectfully from both:

• Jain Dharma understanding
• Scientific / practical reasoning
