Do you cross your heart and hope to die? I won't believe you otherwise.

除非你心划十字，以死起誓，否则我不会相信你的。

After that, all you can do is cross your heart and pray to heaven and hope for the best.

然后，你能做的就是画十字在胸前还有祷告愿天神能保佑你。

Do not content with showing friendship in words alone, let your heart burn with loving kindness for all who may cross your path.

不要仅满足于用言词去表达友爱，让你的心对所有与你交往的人，都燃烧着熊熊的爱火。
