維摩經略疏垂裕記 8.95

8.95

二、「今圓」下，顯是，二：初、通取圓因。「發軫」者，軫，車也。《文選》云「發軫清洛內」。「金沙大河」者，《大經》因佛說一切江河必有迴曲，文殊遂難。佛云：「於此三千世界有渚名尼拘耶，其渚有河端直不曲名娑婆，猶如直繩直入西海。」今以江河迴曲喻前教，金沙直入喻圓頓觀法，即障是德如直入海。

2. From 'Now the Perfect' down, revealing what is correct, in two: first, broadly taking the cause of the Perfect [teaching]. 'Setting forth the carriage': zhen means a carriage. The Wen Xuan says: 'Setting forth the carriage within the clear Luo.' 'The Great River of Golden Sand': in the Mahāparinirvāṇa Sūtra, because the Buddha preached that all rivers must have bends and curves, Mañjuśrī thereupon challenged him. The Buddha said: 'In this trichiliocosm there is an islet named Nigrodha; on that islet there is a river, straight without bends, named Sahā, like a straight plumb-line entering straight into the western sea.' Now the bends and curves of the rivers illustrate the previous teachings, while the golden sand entering straight illustrates the contemplation method of the Perfect and Sudden, wherein obstacles are themselves virtues, like entering straight into the sea.
