extensive and brief　広略 That is, the extensive and brief descriptions of ultimate reality. ‘Extensive’ is the ultimate reality expressed in words and concepts. ‘Brief’ is that which is opposite to the ‘extensive’, and here means the ultimate reality inexpressible by words and concepts. This notion first appears in Vasubandhu’s Treatise on the Pure Land, and under Tan-luan, it undergoes further development in his Commentary on the Treatise. Here, ‘extensive’ represents the description of reality in words and concepts such as Amida and the Pure Land and its adornments, and ‘brief’ is formless reality, which is beyond conceptual understanding. In other words, ‘extensive’ implies the twenty-nine adornments of Amida, bodhisattvas, and the Pure Land, and ‘brief’ implies their essence expressed here as the phrase purity, or the phrase one-dharma. Furthermore, the term ‘brief’ is synonymous with the phrase ‘one-dharma’. See ‘the phrase “one-dharma”’.
