I came across this article in Lions Roar,
I think it is a really good question. In a way the dharma contains a lot of old material, things that were relevant 2500 years ago such as gods and cosmology. But do we dare to formulate a new version? It is difficult to know what is essential to the teaching, and what is merely window dressing that has accumulated through people’s superstitions.
I thought the article was interesting because it takes a different view, that we should consider any current update to be no different from past Buddhist adaptations to different cultures. Very refreshing, and relatively liberated.
