注維摩詰經 4.316

4.316

肇曰：大乘萬行分為二業，以智為行標，故別立智業；諸行隨從，故總立德業。凡所修立，非一業所成。而眾經修相淨土，繫以德業；知念說法，繫以智業。此蓋取其功用之所多耳，未始相無也。

[Seng]zhao says: The myriad practices of the Mahāyāna are divided into two kinds of deeds: taking knowledge as the hallmark of practice, deeds of knowledge are distinctively established; because the various practices follow along, deeds of virtue are collectively established. All that is cultivated and established is not accomplished by a single kind of deed. Yet the various sūtras tie cultivating marks and purifying lands to deeds of virtue, and tie knowing thoughts and expounding the Dharma to deeds of knowledge. This merely draws upon where their functions predominate; they are never without each other.
