首楞嚴義疏注經 8.227

8.227

菩提，佛覺也。前則若出未出，如火前相，名之為煖；今如火出木盡，灰飛煙滅，故云善得通達。故此初地名通達位，盡佛境界理顯也。以得無分別智，善達法界一真平等，離能所相，故《唯識》云「若時於所緣，智都無所得，爾時住唯識，離二取相故。」又云「善達法界，得一真平等，乃至得遍行真如，離異生性障，修檀波羅蜜增上。」言遍行者，以此真如遍在一切諸行法中，而今證得，自利利他得自在故，名歡喜地。《華嚴》、《仁王》廣明其相，今不具錄，下皆倣此。

Bodhi is the Buddha's awakening. Previously it was as if about to emerge yet not emerged, like the sign prior to fire, named Heat; now it is like fire emerging and wood consumed, ash flying and smoke vanishing, hence it says "skillfully penetrates." Therefore this first ground is named the stage of breakthrough; "fully exhausting the Buddha-realm" means the principle is revealed. Because one attains non-conceptual wisdom and skillfully penetrates the single true equality of the dharmadhātu, leaving the characteristics of subject and object, Vijñaptimātratā says: "When regarding the object, wisdom is completely without attainment; at that time one abides in consciousness-only, free from the characteristics of the two graspers." It also says: "Skillfully penetrating the dharmadhātu, attaining the single true equality, up to attaining all-pervading tathatā, leaving the obstacle of the nature of ordinary beings, and cultivating the dāna-pāramitā predominantly." Speaking of "all-pervading": because this tathatā pervades all conditioned dharmas and is now realized, attaining sovereignty in benefiting oneself and benefiting others, it is named the Joyous Ground. The Avataṃsaka and Benevolent Kings extensively clarify its characteristics; they are not fully recorded now, and the following stages are all modeled on this.
