This is Bhikhu Anālayo’s new article on the term āsava (translated as ‘influxes’) in November Insight Journal .
He is pointing to the story where the Buddha teaches king Pasenadi how to lose weight, thereby making the point that the modern use of mindfulness techniques ‘merely’ for health purposes does indeed have a precedent in the EBTs. And also, in the relevant sutta we see the world’s first professional mindfulness trainer being established in his position!
