He lost his sanity and became sapless and sand-blind.

他失去了明智，变得没有生气和一半肓了。

The tender shoots and the expanding flowers are nipped and withered, and of a vine that yearned to stretch its tendrils round the world there is left but a sapless stump.

柔嫩的枝条和盛开的花朵都被咬断并枯萎了， 而一棵渴望将其卷须伸展到世界各地的葡萄树只剩下一个没有汁液的树桩。
