It is said that the eye disease of Emperor Sanjo was his fault, and the "Hobutsushu" (A Collection of Treasures) stated that lightning that fell on the Seiryoden (the residential palace of the emperor) in 930 was caused not by SUGAWARA no Michizane but by him.
特に三条天皇の眼病は彼のせいであるとされ、また『宝物集』では延長_(日本)8年（930年）の清涼殿への落雷も菅原道真ではなく彼の仕業であるとされている。
