維摩經玄疏 3.188

3.188

First, regarding the sūtras explaining different numbers of stages: For instance, the Avataṃsaka Sūtra has only forty-one stages—the thirty minds, the ten grounds, and the ground of the Buddha. The Yingluo jing explains fifty-two stages. The Renwang jing explains fifty-one stages. The newly translated Suvarṇaprabhāsa, the Prajñāpāramitā of King Suvikrāntavikrāmin, and the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra explain only the ten grounds and the ground of the Buddha, not opening the thirty minds. The Mahāparinirvāṇa Sūtra explains the five practices and the ten merits, through which one infers and opens the thirty minds and the ten grounds. The various treatises explaining the stages of grounds differ in being more or fewer, which is entirely due to relying on different sūtras.
