Sourcing a prajñāpāramitā statement In the Madhyamakaśāstra, Venerable Vimalākṣa quotes the Pañcaviṃśatisāhasrikāprajñāpāramitāsūtra:
菩薩有我亦非行無我亦非行
&quot;If the bodhisatva has a self, he cannot act. With no self too, he cannot act.&quot;
T1564.24b29
I've read this before, but finding it in the sūtra is proving daunting. Where in the root sūtra can we find the passage the Venerable is quoting? Also, where can we find the corresponding section of the Mahāprajñāpāramitāśāstra commentary concerning this statement?
The &quot;root&quot; is a passage from the 18th chapter of the MMK:

諸佛或說我 或說於無我 諸法實相中 無我無非我 諸法實相者 心行言語斷 無生亦無滅 寂滅如涅槃 一切實非實 亦實亦非實 非實非非實
是名諸佛法
All Buddhas either speak of self or speak of no self. All dharmas’
true aspect, within this, there is neither self nor no self. All
dharmas’ true aspect is defined as mental activity’s and spoken
language’s ending.There is no arising and no cessation, there is calm
extinction, such is nirvāṇa. All is real, all is unreal, all is both
real and unreal, all is neither real nor unreal: this is called all
Buddhas’ dharma.
