The Dharmakāya in Early Buddhist Texts

[Coëmgenu]

自覺

Also, original enlightenment?

Nah I think that part of the translation is actually accurate "the Tathāgatāni of their own awakening know this" or "The Tathagata themselves know realise this".

Indeed, that was a more wistful suggestion

[Coëmgenu]

法住、法空、法如、法爾
dharmāṇām pratiṣṭhitā dharmāṇām śūnyatā dharmāṇām tathātā dharmāṇām tiṣṭhitā

The SF fragments, representing a recension that is parallel, though by no means identical, to the SA/ZA being discussed here, has the following expression:

iti yātra dharmatā dharmasthititā dharmaniyāmatā dharmayathātathā

It would appear that the Sanskrit (Marcus Bingenheimer argues, I will find the citations shortly, for a Prākrit original to the SA material, though some others controversially argue for Gāndhārī) may have had grammatical compounds something more akin to:

法住、法空、法如、法爾
iti yātra dharmatā dharmasthititā dharmanairātmya dharmayathātathā
