Note 931 — Chapter L
Reading edition
From 1026 onwards see the chronological tables of Sum-pa translated by Sarat Chandra Das in J.A.S.B. 1889, pp. 40-82. They contain many details, especially of ecclesiastical biography. The Tibetan system of computing time is based on cycles of sixty years beginning it would seem not in 1026 but 1027, so that in many dates there is an error of a year. See Pelliot, J.A. 1913, I. 633, and Laufer, T'oung Pao, 1913, 569.
