1. The loan becomes NPA only because you defaulted paying the EMI.
2. If that is so then clear the EMI first and regualrise the loan account.
3. If the loan account is regualrised once again the SARFAESI proceeding will stop.
4. If on your proposal to make the payment the bank refuses to accept the proposal then file an application under section 17 of the SARFAESI Act seeking injunction on sale.
