華嚴一乘成佛妙義 1.28

1.28

又依六相總別義即是一乘，隨相別布義即是三乘。此約教分說其一乘十地之法，盡其三世已通究竟。此據證說。記云：於此十地用六相緣起陀羅尼法者，即是無礙自在十地，故為一乘也。若隨法空智分位用勝劣出為十地者，即是三乘。此約教分說者用六相教。今法緣起方得為一乘者，此約教分而釋。若約證分者，自在盡三世通究竟處為證位也。

Furthermore, relying on the universal and particular meanings of the six characteristics, this is the One Vehicle; relying on the meaning of their separate distribution according to marks, this is the Three Vehicles. This is explained in terms of the division of teaching, wherein the Dharma of the ten stages of the One Vehicle exhausts the three periods of time and is thoroughly ultimate. This is explained based on realization. The Record says: 'To apply the dhāraṇī-dharma of the dependent origination of the six characteristics to these ten stages is precisely the unimpeded and sovereign ten stages, and is therefore the One Vehicle. If one brings forth the ten stages based on the superiority or inferiority of the functional status of the wisdom of dharma-emptiness, that is the Three Vehicles.' What is explained in terms of the division of teaching employs the teaching of the six characteristics. That it is only when phenomena dependently originate that it constitutes the One Vehicle is explained in terms of the division of teaching. In terms of the division of realization, the sovereign exhaustion of the three periods of time pervading the ultimate locus is the stage of realization.
