Heaven :It is a place of perfect happiness and peace, being with all your favorite people, feeling completely safe, and never feeling sad, sick, or bored. like  as the best day ever that never ends.

Purgatory is like a "waiting room" or a place to get ready. It’s a place where people get "cleaned up" from their mistakes before they enter Heaven. It’s not a permanent home; it’s just a stop along the way. The Goal is to become the very best version of yourself 

Hell is the opposite of Heaven. It is a place where there is no love and no happiness, because the person chose to walk away from goodness and never come back. It’s a place for those who stayed mean and didn't want to be part of the "good team."
