大方廣佛華嚴經隨疏演義鈔 10.43

10.43

疏「萬行例然」者，即約行說純雜，通於事理事事無礙，及單約事行也。約事事無礙者，如一施行一切皆施，名純。施中具於諸行，名雜。

Regarding the Commentary's line: 'The myriad practices are likewise': this speaks of purity and mixture in terms of practice, applying to the non-obstruction of phenomenon and principle, the non-obstruction between phenomena and phenomena, and solely to phenomenal practice. In terms of the non-obstruction between phenomena and phenomena, for example, practicing a single practice of giving such that all practices are giving is called purity; that giving contains within it all practices is called mixture.
