The original should be taken from Sandaishu (three major collections of Japanese poetry; Collection of Ancient and Modern Japanese Poetry, Later Collection of Japanese Poetry and Collection of Japanese poetry compiled by imperial command), "Ise Monogatari" (The Tales of Ise), or "Sanjurokunin kashu" (Thirty-Six Anthologies), not from recent poetry (from the view point of Teika).
本歌として採用するのは、三代集・『伊勢物語』・『三十六人家集』から採るものとし、（定家から見て）近代詩は採用しない。
