I think the authors of the Lotus Sutra wanted to shock the shit out of their readers, to slap them in the face or pour buckets of cold water on them, a sort of a shock and awe of Buddhism. First, the ultimate truth of Buddhism is that we are all capable of becoming Buddhas. Second, there isn’t a whole bunch of petty differing ways of going about attaining Buddhahood. Third, we should quit expecting others to do for us what we are fully capable of doing for ourselves.
