七言绝句 押词韵第七部
遍访乾坤总惘然，天垂日月寂无言。
海涛悲涌深蓝色，不答凡夫问太玄。
注：Earth could not answer; nor the Seas that mourn
In flowing Purple, of their Lord forlorn;
Nor rolling Heaven, with all his Signs reveal'd
And hidden by the sleeve of Night and Morn.
In flowing Purple, of their Lord forlorn;
Nor rolling Heaven, with all his Signs reveal'd
And hidden by the sleeve of Night and Morn.
