calamity of invasion from foreign lands ［他国侵逼難］ ( takoku-shimpitsu-nan): Also, foreign invasion. One of the seven disasters described in the Medicine Master Sutra. In On Establishing the Correct Teaching for the Peace of the Land, written in 1260, Nichiren predicted that this and the calamity of revolt within one’s own domain would occur if the rulers of Japan failed to accept the correct teaching. His prediction of foreign invasion was realized in the form of invasions by the Mongol Empire in 1274 and in 1281. See also seven disasters.
