3.158

四後三行者，配第四住中三種法身。謂言說法身配尊重行，於佛言教生尊重故。智相法身配善法行，以真如無為是真善法故。福相法身配真實行，以持經之福無漏真實故。

On "the fourth to the latter three practices": these correlate with the three kinds of Dharmakāya in the fourth dwelling. That is, the Dharmakāya of verbal expression correlates with venerating practice, because veneration is generated toward the Buddha's verbal teaching. The Dharmakāya of the marks of wisdom correlates with good Dharma practice, because unconditioned tathatā is the true good Dharma. The Dharmakāya of the marks of merit correlates with true and real practice, because the merit of upholding the sūtra is untainted, true, and real.
