維摩經玄疏 1.113

1.113

答曰：三藏教多說三悉檀，少說第一義；般若多說第一義，少說三悉檀。復次，般若雖說三悉檀，皆與第一義相應，若說諸大乘方等，或合說，或別說也。

Answer: The Tripiṭaka teaching mostly expounds the [first] three siddhāntas and rarely expounds the paramārtha; Prajñā mostly expounds the paramārtha and rarely expounds the [first] three siddhāntas. Furthermore, although Prajñā expounds the [first] three siddhāntas, they all correspond with the paramārtha. When expounding the various Mahāyāna Vaipulya [sūtras], they are either expounded combined or expounded distinctively.
