Over the door mantra plaque, with kalachakra and Om Mani Padme Hum logos. Gold-plated metal mounted on wood.
Both A and B plaques are the same mantra, but in slightly different style of writing of the Lantsa script.
It's the Liberation Upon Seeing (Sight) Mantra.
It is said that those who see this script will not experience the three lower realms, and will be liberated from the fear of falling into the lower realms; will be purified of the five poisons and will be freed from the results of one's karma; will be freed from the fear of remaining in samsara.
