See Sabrina's comments. It strikes me that surrounding the pressure cooker with a dish cloth may pose a fire hazard. It seems to me that either the cooker is defective or that you are operating it incorrectly. As I remember the Mantras are an old fashioned jiggle top pressure cooker so I would proceed as follows:
Make sure that the pressure release hole where the jiggler rests on is open and clear by looking through it and if it is not perfectly, I mean perfectly clear, make sure that it is by cleaning it. Make sure that the jiggler that rests on this tube is clean and that it rocks freely on the pressure release pipe.

Make sure the gasket is clean and where the gasket sits in the lid is clean and the top rim of the cooker is clean. Run your finger along the rim and gasket seating area to see if you can find any bumps etc.
Put a quart of water in the cooker, not food but water only, and carefully assemble the cooker. Bring the cooker up to pressure and see if steam comes out of the gasket or if it comes out from the jiggler.
If steam still comes out of the gasket I would return the cooker. If steam only comes out of the jiggler then you are probably overloading the cooker as Sabrina has suggested. You could leave the jiggler off when you assemble the cooker and try heating the water and see if steam comes out of the pressure release hole and if it does then pull the cooker off the burner until steam no longer comes out and put the jiggler on and return the cooker to the burner to bring to pressure.
If you have overloaded it with beans you may have forced some bean detritus into the small pressure release hole and the cooker is relieving excess pressure through the gasket, which is a dangerous situation.
I don't know if the Mantra has a rubber plug that is designed to blow out if overpressure results or not. Look and see.

Good Luck
