Death, Heaven, Hell and Purgatory: Catholic Teaching

Heaven:

Fr. Mike Schmitz: How to get to Heaven

Hell:

Fr. Mike Schmitz: Hell is Real

Purgatory:

There are a couple of good videos with some more detailed answers (see below), but the easiest, simplest explanation is 

"Purgatory isn't a just a place, it is more of a process, like a car wash.  Imagine a man who gets his car cleaned before he takes out a woman for their first date.  Just like a car wash is a cleaning process for a car that is going somewhere where it is important for it to be clean, purgatory is a cleaning/purification process for our souls before we enter into Heaven."
