End, disease, let go, cessation
Coffin, if located very close to the persons card, it infalibly means severe illness, demise or entire loss of wealth. Further away from the persons card, it is far less dangerous.
In modern interpretation the casket refers to the completion of a development and the beginning of a new one. Given the knowledge, that nothing lasts forever, you should courageously face a fresh start, even if this means to relinquish and idle wish.
