Neon Genesis Evangelion is my favorite anime ever, and I recently found one of my favorite articles again. I read it a few years ago, but couldn't find it again until now. Titled "Self and (M)other: Apocalypse as Return to the Womb in Neon Genesis Evangelion", the article heavily discusses the rich religious and Freudian symbolism in the ending of the show + End of Evangelion. It's a fairly short article, only taking up to 10 minutes to read, but to anyone who is a fan of the show, I highly recommend it. Here's a link:
