Which yeah. That sort of thing might be a good and interesting lens to view Bleach through. Japanese Buddhism too, honestly. Especially since the series is so death centric and since death tends to be the realm of Buddhism in Japan. I've had that explained to me as...Death causes grief, anger, hatred...A lot of very hard emotions. This generates massive amounts of kegare. Kami thus don't deal with that side of things because the massive amounts of kegare. Some even explain the reason for why you do not burn incense at or near a kamidana as being because it reminds kamisama of death. But we conveniently have these bodhisatta and monks who are totes cool with dealing with all of that shit. So they get to handle death and grief, while the kamisama and Shinto can handle the side of the equation that Buddhism often neglects. Which is life and living a good life. I've had Shinto explained to me by books and people as being...a lifelong attempt at living life well and full. Living a good life. It is not focused on dogma and cannot be described as orthopraxy. It is living and trying to embody the spirit of kami from which all beings come from (and which we all are).
