仁王般若經疏 3.133

3.133

"The sun and moon losing their courses, seasons running contrary, or a red sun appearing, a black sun appearing, two, three, four, or five suns appearing, or solar eclipses without light, or a single halo, or two, three, four, or five halos appearing around the solar disk—when such strange portents occur, reading and reciting this sūtra constitutes [the remedy for] the first calamity."
