Animekritic has one of the most thoughtful blogs I’ve read. He frequently addresses spirituality in anime, among them a really fun post about Faye Valentine, Rei Ayanami, and enlightenment. In it, he makes the connection between the two famed characters through their shared voice actress, Megumi Hayashibara. Then, based on monologues each give, explains where each is in progressing toward enlightenment in Zen Buddhism, based on a commentary on the topic.
Go check it out – it’s a fun read!
