Is there a sutta which answers where a nirvanaised consciousnesses is after death and comapres it to a fire going out? I thought there was, but can't find it. Sounds like Vacchagota mashed up with the fire sermon . I'm asking because I like the image, and it almost appears in some modernist poetry. Failing a sutta, any zen discourses. Failing that, anywhere in the canon. Failing that, any important Buddhist, living or dead. Failing that an academic.
