Answer

If someone says “Sātā mā̃ chho?” / “Sata main hu?” in a Jain context, they are usually asking:

“Are you in peace/well-being?” or “Are you doing well?”

A respectful reply can be:

• “Hā̃, sātā mā̃ chhu.” — Yes, I am well/peaceful.
• “Bhagwān nī krupā thī sātā mā̃ chhu.” — By Bhagwan’s grace, I am well.
• “Hā̃, sātā mā̃ chhu, tame sātā mā̃ chho?” — Yes, I am well; are you well?
