維摩經略疏垂裕記 4.98

4.98

四、示遊四衢。《爾雅》云「路四達謂之衢。」郭璞曰「交道四出也。」《列子》曰「人之遊也，觀其所見。我之遊也，觀其所變。」豈法身大士所遊而無所表耶？

Fourth, manifesting roaming the four thoroughfares. The Erya says: 'A road reaching in four directions is called a thoroughfare [qu].' Guo Pu says: 'An intersection issuing in four directions.' The Liezi says: 'When ordinary people roam, they observe what they see. When I roam, I observe what transforms.' How could what the Great Being of the dharmakāya roams not signify something?
