TMingyur wrote:"Entrance" is a metaphor because it is not like "to enter a room", i.e. first being "outside" and then - having passed the entrance - one is in the room. It is not like this. "Entrance" is the collection of causes and conditions that lead to cessation of past, cessation of future and cessation of present.
This is one root of your various misunderstandings. Cessations cannot be caused nor conditions. Causes and conditions do not lead to cessations, they only lead to further causes and conditions. A cessation is the absence of causes and conditions.
