²¹Though see Samyutta Nikaya 22.95, where the Buddha clearly talks about a general emptiness of the Mahayana kind, while using a slightly different terminology: he does not use the word suññatā/śunyatā which is the term usually translated as emptiness, and became prominent in later texts. See also Majjhima Nikaya 121 for a very different early view on emptiness, and Williams (2008b, p. 54).
