妙法蓮華經玄義 1.61

1.61

Wishing to expound this Dharma, he first startled and moved them with supernatural power, and thus it is called 'all sovereign supernatural powers'. Having seen the transformations, they were awakened and full of yearning, so that he could expound the teaching for them. The teaching interprets the real mark, and thus it is called the 'secret treasury'. Receiving the teaching and practicing it, there are causes and fruits, and thus it is called 'exceedingly profound matters'. Wishing to distinguish the four meanings as to their sameness and difference with other sūtras, he next clarified the characteristics of the teaching.
