摩訶止觀 2.75

2.75

色、色者如虛空，名「空三昧」。不得此空，名「無相三昧」。無能無所，名「無作三昧」。何但三諦、六度、三空？一切恒沙佛法皆例可解。觀色塵既爾，餘五塵亦然，六受、六作亦如是。《法華》云：「又見佛子，威儀具足，以求佛道。」即此義也。

Form-matter and the one who forms being like empty space: this is called śūnyatā-samādhi. Not grasping this emptiness: this is called animitta-samādhi. Being free from subject and object: this is called apraṇihita-samādhi. How could it merely be the three truths, six pāramitās, and three emptinesses? All Buddha-dharmas as numerous as the sands of the Ganges can be understood by this analogy. Since contemplating the dust of form-matter is like this, the remaining five dusts are also like this, and the six perceptions and six activities are also like this. The Lotus Sūtra says: 'Again I see the Buddha's sons / fully endowed with dignified comportment / to seek the Buddha path.' This is precisely the meaning.
