維摩經玄疏 1.86

1.86

First, clarifying that using the four siddhāntas gives rise to the Tripiṭaka teaching: with respect to "arising arising is ineffable," the Buddha uses the four siddhāntas to respond to the śrāvaka disciples of dull faculties with heavy obstacles, who take pleasure in lesser virtues produced by the Dharma of the ten causal conditions of the Small Vehicle, expounding the four noble truths of arising and ceasing of the Tripiṭaka teaching to teach the śrāvakas and dull-facultied bodhisattvas. Therefore the Lotus Sūtra says: "The quiescent mark of all phenomena cannot be expressed in words. By the power of skillful means, it was expounded for the five monks; this is called the turning of the wheel of Dharma."
