I want to know the answer to the following question:
Authors Bronkhorst and Anderson claim the four truths bacame a substitution for what?
All the background I'm provided with is that "According to both Bronkhorst and Anderson, the four truths became a substitution for prajna, or "liberating insight", in the suttas in those texts where "liberating insight" was preceded by the four jhanas.". Is that enough to answer the question?
Answer: yes
