Oh also: David's chart, which puts Sutra as renunciate and Tantra as exultant () seems (to my very new understanding) to be in contradiction to the chart from Rigpa Wiki () with the "outer tantras" as ascetic. ascetic ≠ renunciate?
Realized today I really don't have a good map of the different schools of Buddhism. Found this excellent chart by differentiating Sutra & Tantra. Now wondering: • Tantra = Vajrayana ? • Sutra = {Mahayana, Theravada} ? • what else is there?
