How to translate this Chinese word:顿悟

Hello,dear poddies

It has puzzled me for at least 3 days when trying to find the English equivalent about this Chinese word:顿悟 dun4wu5

他顿悟了一切.Suddenly,everything is clear to him.......

I just paraphrased the sentence.....it's acceptable but not recommendable for language learning...

Can someone tell me how to translate 顿悟

顿means "suddenly",or"for a short while",as in停顿(pause for a few moments) 悟 means understand,as in 领悟,醒悟,觉悟...

So.....
