觀彌勒上生兜率天經贊 2.29

2.29

贊曰：此有二嚴。四地修得菩提分法，慧焰增故，百行助成感百億光。五地作四諦觀出生死泥，智花敷故，內解五明、外感五五百億華。

The commentary says: Here there are two adornments. On the fourth ground, through cultivation one attains the dharmas conducive to awakening; because the flames of wisdom increase, the hundred practices assist in bringing it to completion, karmically generating the hundred billion [beams of] light. On the fifth ground, one performs the contemplation of the four noble truths and emerges from the mire of birth and death; because the flowers of wisdom blossom, one internally understands the five sciences and externally karmically brings about the five [times] five hundred billion flowers.
