“Haadshant pad” (often said as “hadd‑shant pad”) is not a specific Jain sutra, but a descriptive Jain term used in pravachans / literature.

In simple words:

• “Haad / hadd” = limit, boundary
• “Shant” = completely peaceful
• “Pad” = state or spiritual position

So “haadshant pad” means: a state of such perfect peace that it is beyond all limits – the ultimate, final peace of the soul.

In Jain dharma this points to the Siddha state:

• All karmas are completely destroyed
• No anger, ego, deceit, greed
• No birth and death cycle left
• Only pure, infinite knowledge, faith, bliss and energy remain

So when someone says, “Atma ko haadshant pad prapt ho,” they are basically praying for the soul to attain moksha / siddha-pad – the highest, boundary-less peace.
