大方廣佛華嚴經疏 4.25

4.25

Sixth, proclaiming all dharmas like spreading great clouds is the vow-body. "Proclaiming dharmas" means raining down the great rain of Dharma to sever all doubts. Therefore a later passage of the sūtra states: "The vow-power of Vairocana Buddha / Pervades the dharmadhātu; / In all lands / He constantly turns the unsurpassed wheel." However, of the two lines in the sūtra, the former is the teaching and the latter is the metaphor; the text contains many meanings: first, the cloud is a metaphor for the body, the rain is preaching the Dharma, and the teaching and metaphor reflect and imply one another. Furthermore, he first raises the clouds of compassion and afterward showers the rain of Dharma. The moistening from a single cloud and a single rain is not uniform; also, according to the capacities and aptitudes of beings, the clouds and rains differ respectively, concealing dust and veiling the sun, extending over all without deliberation, and so forth.
