Namaste pathless,
thank you for the post.
yes, i am a vegetarian and am quite happy to be one. i must admit that it's much easier to be a vegatarian now than it was in the past.. especially for an individual like myself that used to be "meat and potatoes" sort of person.
as an aside.. if you've not tried the Quron line of vegetarian products, you don't know what you are missing! they are the best.. and, funnily enough (given the reputation) they are an English company
i did some investigation about the onions, garlic and leeks and have found that, pretty much, that is a speical diet that is encouraged in the Krishna sects. in my particular school, owing to it's northern origins, these aren't an issue. from what i've read of the Krishna dietary restrictions, these three are singled out because they make a person "spicy". they don't really say what that means
but they do go on to talk about how it can cause indegestion and will interfere with their meditational practice.
my understanding of the mushroom thing is it is because it's a living creature, although a fungi. in my experience, i've not seen this one much observed... i would tend to suspect that this was simply to prevent people from eating bad 'shrooms and dropping dead.
we do have to sustain ourselves and, even a strict vegan diet, will cause other beings to die. the insects living in the ground or on the plant etc... so, we need to keep these things in a bit of perspective, in my opinion.
do i think it's absolutely reuquired? no, not at all. it is recommended for most but is not required for all.
