Answer

Yes. If someone asks you “Satamāī?” during fasting, it is appropriate to reply:

“Dev Guru Pasāye.”

Explanation

In Jain tradition, “Satamāī?” is a respectful way of asking whether your fasting/tapas is going well and whether you are in good spiritual stead.

The reply “Dev Guru Pasāye” means:

“By the grace/blessings of Dev and Guru.”

Here:

• Dev refers to Arihant Bhagwan / Tirthankar Bhagwan.
• Guru refers to the Jain Sadhu-Sadhvi Bhagwant or spiritual teachers.
• Pasāye means by grace or blessings.

Spiritual Understanding

This reply shows humility. Instead of taking pride in the tapas, the person acknowledges that the strength to fast comes through the blessings of Dev, Guru, and Dharma.

Takeaway

So yes, when someone asks “Satamāī?”, you may respectfully reply:

“Dev Guru Pasāye.”
