17.341

基云：謂四禪寂靜解脫得無色定入滅定，滅定是寂靜解脫。九果者，即四沙門果中初三及六神通，不取第四果者即漏盡通故。已下結上所明有五清淨，如次屬當，初明六作意是欲界心故，名不定地清淨，餘四可知。

[Kuiji] said: That is to say, from the tranquil liberation of the four dhyānas, one attains the formless absorptions and enters the absorption of cessation; the absorption of cessation is the tranquil liberation. As for the 'nine fruits', these are the first three among the four fruits of asceticism, together with the six superknowledges; the reason the fourth fruit is not taken is that it is the superknowledge of the destruction of contaminants. Below this, [the text] concludes what was clarified above, that there are five purifications, which correspond in sequence: the first explains that the six mental applications are minds of the desire realm, and therefore it is called purification of the unfixed stage; the remaining four can be understood.
