2.95

前二句明以智證理，後二句證理之相。兔馬者，即經中所說象、馬、兔同渡一河，河自無殊，得有淺深，以喻三乘同入法性，淺深三異。今意云：以所證真諦本無兔馬淺深之跡以軌般若，般若亦無差別無窮之鑒照也。

The first two lines explain using wisdom to realize principle; the latter two lines explain the characteristics of realizing principle. "The hare and the horse" refers to the sūtra's teaching of the elephant, horse, and hare crossing the same river together; the river itself has no differences, but their attainment of depth varies, which serves as a metaphor for the three vehicles entering the dharmatā together with three different degrees of depth. The present meaning is: using the realized ultimate truth, which originally lacks the traces of the hare and horse's shallow and deep depths, to regulate prajñā, prajñā likewise lacks diverse and inexhaustible discriminations in its mirror-like illumination.
