1.59

即是真心者，顯非斷滅。恐聞一切諸法泯之皆無，諸法既無應成斷滅。故此顯云即是真心。然此心與上心字不同，上是緣生妄心，即前夢識也；此是常住真心，即前鏡心也。為揀別故，故特言真，以一切諸法皆依此心，若離此心無別有法。故經云：「一切世界因果微塵因心成體。」心之所現名曰依他，執之為實乃名遍計，依計既泯即是圓成。如繩依麻有蛇託繩生，繩蛇既亡則麻著矣！此是疏主出般若之密意。若據經文，即但言諸法皆空，不言即是真心。故下文云：「離一切相即名諸佛」，文雖不彰義實如此。若法性宗，即直於諸法空處顯出真心。故《圓覺經》云：「種種幻化皆生如來圓覺妙心，猶如空華從空而有」，乃至云：「諸幻盡滅覺心不動」，故云即是真心也。

Regarding 'is precisely the true mind': this shows that it is not annihilationism. Fearing that hearing that all phenomena are obliterated into non-existence might cause one to think that, all phenomena being non-existent, it must result in annihilation, he therefore reveals here that it 'is precisely the true mind'. However, this 'mind' differs from the word 'mind' above: the former is the deluded mind arisen from conditions, namely the previously mentioned 'dream-consciousness'; this is the eternally abiding true mind, namely the previously mentioned 'mirror-mind'. To distinguish them, he specifically says 'true', because all phenomena depend on this mind; apart from this mind, there is no other phenomenon. Hence a sūtra says: 'The causes, effects, and subtle dust motes of all worlds take the mind as their essence.' What is manifested by the mind is called the dependent [nature]; grasping it as real is called the imagined [nature]; once the dependent and imagined are obliterated, that is precisely the consummate [nature]. Just as a rope depends on hemp, and a snake is imputed based on the rope: once rope and snake are both eliminated, then the hemp is manifest! This is the commentator's disclosure of the esoteric meaning of prajñā. If one relies strictly on the sūtra text, it merely states that all phenomena are empty, without stating that it is precisely the true mind. Thus the text below says: 'Departing from all marks is named the Buddhas.' Although the text does not make it explicit, the meaning is truly such. If according to the Dharmatā School, it directly reveals the true mind at the very locus of the emptiness of all phenomena. Hence the Perfect Enlightenment Sūtra says: 'Various phantoms and illusions all arise from the Tathāgata's wondrous mind of perfect enlightenment, just as sky-flowers exist based on space,' up to saying: 'When all illusions are completely extinguished, the enlightened mind remains motionless.' Hence it says 'is precisely the true mind'.
