In Jainism, there is no universal scriptural rule that says “Adra is specifically for stopping mango eating.”

What is accepted in Jain practice is this:

• Ahimsa is the main principle
• Food is avoided when it causes more harm to living beings
• Many Jains reduce or stop mango eating in certain seasons or during Chaturmas, depending on local tradition and family achar
• But this is not the same as a fixed rule for “Adra” alone

So, the correct answer is:

Adra is not a standard Jain rule for stopping mango eating. It may be a community or family practice, not a universal Jain injunction.

If you want, I can also explain this in simple Gujarati/Hindi Jain terms.
