仁王經疏 3.476

3.476

釋曰：第二、別列華名。心空華者，四空也，三學之中名為心學。心樹華者，緣生觀也，十二緣生名為華樹。六波羅蜜華者，十地行也。此上三華，如次顯彼三乘法也。妙覺華者，佛果行也，因中說果名妙覺華。

Explanation: Second, separately listing the names of the flowers. 'Mind-emptiness flowers' are the four [immaterial absorptions of] emptiness; among the three trainings, this is called the training of the mind. 'Mind-tree flowers' are the contemplation of conditioned arising; the twelve links of conditioned arising are called the flower-tree. 'Six pāramitās flowers' are the practices of the ten bhūmis. The above three flowers successively reveal the dharmas of the three vehicles. 'Wondrous awakening flowers' are the practices of the Buddha fruit; speaking of the fruit from within the cause, they are called 'wondrous awakening flowers'.
