This view interprets the Nirvana Sutra as 'tsuisetsu' (a re-exposition of the Lotus Sutra sermons), which Buddha gave to people who failed to attend these sermons (or failed to understand their meaning) based upon his Lotus Sutra sermons along with his other previous sermons on temporary truths contained in various Hinayana and Mahayana Buddhist sutras, such as Kegon (Flower Garland), Agon (Agama), Hodo (Expansion) and Hannya (Wisdom).
「追説」とは、『法華経』の会座にいなかった（漏れて覚れなかった）人たちのために、華厳・阿含・方等・般若の小大乗の方便の教えを、『法華経』の意義を含みつつも、さらにもう一度方便の教えを説くことをいう。
