The Sūtras and Treatises Used as Background for the Concept of the Two Kinds of Dharma-Body in Tanluan’s Commentary on the Treatise on the Pure Land

In Tanluanʼs Commentary on the Treatise on the Pure Land浄土論註, we find a passage quoted from Sengzhaoʼs Commentary on the Vimalakīrtinirdeśa 注維摩経. It is applied to the background of the concept of ʻthe two kinds of dharma-body.’ This concept consists of the following five ideas: 1. Buddhas and Bodhisattvas; 2. Buddhaʼs Dharma-nature and Bodhisattvas’ expedient means for saving beings; 3. The two kinds of Dharma-Body （Buddhaʼs Dharma-Body as dharma-nature and Bodhisattvas’ Dharma-Body as expedient means） originate in each other; 4. The inexpressible aspect of Buddhaʼs reality and expressible aspect of Bodhisattvas’ expedients interact with each other; 5. The two kinds of Dharma-Body are to be identified as ‘Dharma.’
