Note 4 — Chapter XXVIII · RÂJAGṚIHA, NEW AND OLD. LEGENDS AND INCIDENTS CONNECTED WITH IT.
James Legge translation
Hardy (M. B., pp. 288, 289) makes the subjects only thirteen, which are still to be found in one of the Sûtras (‘the Dik-Saṅga, in the Śakra-praśna Sûtra’). Whether it was Śakra who wrote his questions, or Buddha who wrote the answers, depends on the punctuation. It seems better to make Śakra the writer.
