I don't think the kosher rules are necessary anymore. They had to do/don't do certain behaviors to get into a spiritual state. A lot of philosophers have been totally vegan, for example, in a lot of different cultures - like abstinence makes the spirit more accessible. Fasting seems to, for sure. Idk... I'm feeling imposter syndrome now... I'm not good at abstinence and I've only barely begun to understand spiritual things... And for that matter, I suspect that anything less than full knowledge is equivalent to complete ignorance. Hungry now... Want meat...
