說無垢稱經疏 6.402

6.402

贊曰：此有三句。作謂造作，因緣和合之所作故。體即有為，雖行無為無作之法，不樂作證。雖觀有為，後終滅盡。無常真如，於善不厭。雖觀苦理，故意受生，利樂一切。大乘無常苦空無我理，如前〈聲聞品〉中已說。

Commentary: Here there are three clauses. 'Action' refers to created activities, what is made through the combination of causes and conditions; its essence is the conditioned. Although practicing the unconditioned dharma of non-action, they do not delight in realizing it. Although contemplating the conditioned, which ultimately ceases in the end, and the tathatā of impermanence, they do not tire of the wholesome. Although contemplating the principle of suffering, they intentionally take birth to benefit and bring joy to all. The Mahāyāna principle of impermanence, suffering, emptiness, and non-self has already been explained above in the 'Chapter on the Śrāvakas'.
