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.’
In Sengzhaoʼs Commentary on the Vimalakīrtinirdeśa, we find expressions similar to the usage of the above-stated notions in 1, 2, and 3. The notion stated in 5 can be seen in the same commentary and in the Great Significance of the Mahāyāna大乗大義章. As for 4, no source can be located for this idea.
