Example Input: Ajahn Sucitto describes the path as "a mandala of interconnected factors that support and moderate each other." The eight factors of the path are not to be understood as stages, in which each stage is completed before moving on to the next. Rather, they are understood as eight significant dimensions of one's behaviour—mental, spoken, and bodily—that operate in dependence on one another; taken together, they define a complete path, or way of living.
Example Output: Who describes the Noble Eightfold Path as "a mandala of interconnected factors that support and moderate each other."?
