It had come to Castiel's attention that he spent rather a lot of time talking about Hell -- in perhaps too great detail -- but he hadn't detailed Heaven. Well, he could rectify that easily enough now that canon has given his mun some idea. He actually kind of smiled at the congregation when he stood before them, today. Which, you know, was kind of creepy, but whatever.
"Heaven," he said, "is Paradise.
My experience with it as an angel will naturally be different from your experience with it after death, but that is as it should be. It should be noted as well that each individual's experience of Heaven will be different as well. Heaven is a construct of all your happiest earthly memories and ideal locations, your own private paradise. All of your loved ones will be there, exactly as you remember them. Or, rather, constructs of your loved ones will be there. They'll be just as you remember them because that is what they are: memories. This is, again, as it should be." He frowned. "At least that's what we're told."
Perhaps it was best not to examine that thought too closely.
"Most angels are assigned to be a support network for the immortal human souls after their arrival -- something I believe many of my brethren might have forgotten. Some angels to watch out for include Zachariah, who has six wings and four faces." Wait. "Or possibly a balding business man." Moving on. "Heaven is built along the Axis Mundi, which will appear as many different things to different people. It is the route one can follow to arrive in the Garden at the center of Heaven. That is where, I'm told, one might have found the Lord, before he . . . wandered off. Now you're likely to find Joshua, the keeper of the Garden. God talks to him." Castiel clearly didn't understand why Joshua got that lofty privilege. Dude was just a gardener, after all. "Anyway, the important thing is that you remain good, so you can get into Heaven. Where you'll have to dodge certain angels, and be surrounded by imaginary representations of your loved ones, whom you will likely never meet in person again."
[ooc: I love my canon. OCD coming up! And away we go.]
