Hi Siebe,
Question is, how reliable is Nagasena’s work? He was a Sarvastivadan monk. Not saying Sarvastivada is bad. I’m just curious how could he be so sure that the wounding of Buddha’s foot was not a kamma vipaka.
I read a dhamma book (written by a Chinese bhante) which is referenced to Apadàna of the Khuddaka Nikāya. Inside this book, the bhante mentioned about the 12 major kamma vipaka suffered by the Buddha. It is written in Chinese though. Mentioned in the book were accounts of the wounding of the foot from the rock splinter, back pain, dysentery, ascetic practice etc. were all attributed to the Buddha’s previous kamma.
