Perhaps the order of the sentence isn't correct. I've only seen "我轻轻的走了，正如我轻轻的来" The sentence is part of a famous poem from 徐志摩（xu2 zhi4 mo2）, a wellknown poet. The sentence just means what reganmian520 has translated: "I leave here silently, as I came here".

It's from a famous Chinese poet named Xu Zhimo. you can read the entire version here: http://www.hudie.org/wenxue/pinglun/huaijiu/kangqiao.htm

the original sentence is 轻轻的我走了，正如我轻轻的来 from Xu Zhimo i think the sentence you said is made for fun ,the author just wanted to show his humor,so he made "来"and "走" exchanged

I left here silently,as I came here.
