67.94

案僧亮曰：報得色界五陰者，上言色界法，即明報也。寶亮曰：煖法既有為有漏，由能作因報得色界，云何得為無漏道相耶？

Sengliang comments: Regarding 'karmically obtaining the five aggregates of the form realm': the previous mention of dharmas of the form realm refers precisely to karmic retribution. Baoliang comments: Since the dharma of heat is conditioned and defiled, and can serve as a cause to karmically obtain the form realm, how can it serve as a sign of the undefiled path?
