仁王經疏 3.482

3.482

釋曰：第二、緣義定也。於中有二：初明三定、後顯三勝。此即初也。知有漏定，名世諦三昧。知無漏定，名真諦三昧。知非安立真如，名第一義諦三昧。

Explanation: Second, the samādhis focused on the truths. Herein there are two [parts]: first, explaining the three samādhis; second, revealing the three excellences. This is the first. Knowing the defiled concentrations is called the worldly truth samādhi. Knowing the undefiled concentrations is called the ultimate truth samādhi. Knowing non-posited tathatā is called the paramārtha-satya samādhi.
