一切有为法，如梦幻泡影

There is a very convenient example in modem technology. The old motion picture film is actually made up of many reversal films; the first picture film has no connection whatsoever with the second picture film, but due to the speed at which they are rolled out (twenty-four films per second), we do not notice where one picture ends and the next begins. We mistakenly think when a person in an image is walking and talking, it is one continuous motion; we do not expect the connecting images to be formed by many separate films. An illusion is produced because our eye cannot perceive matter of a subtle nature. For scientists and philosophers, this logic should be easy to follow.

其实，现代科技已经为我们提供了一个非常方便的比喻：过去的老式电影胶片，实际上是由一帧一帧的反转片组成的，其中第一帧图像与第二帧图像，完全没有关联，但因为播放的速度比较快（每秒钟二十四帧），所以我们的肉眼无法分辨其间的差别。我们会以为，画面上一个人走路和说话的动作，完全是连贯一体的，绝对想不到这些连续的画面，是由很多没有关联的胶片组成的。因为我们的眼睛没有察看细微物质的能力，所以产生了连贯的幻觉。我想，无论是科学家，还是哲学家，都能够非常容易地了解上述逻辑。

Thus, Buddhism believes all phenomena which arise and cease due to causes and conditions are like a dream, like magic, like a water bubble, like shadow. They are all unreal and illusory.

所以佛教认为，一切有为法，也即有生灭、有因缘的东西，皆如幻、如梦、如泡、如影，都不真实，都是幻觉。

However, from the standpoint of relative truth, if we want to survive and live a normal life, we need the illusion. If this illusion is shattered, the basis of our survival and our beliefs will collapse.

但从世俗谛的角度来说，我们要生存，要过正常的生活，就需要这些幻觉。如果打破了这些幻觉，就没有生存的基础，我们所有的理念，都会分崩离析、彻底瓦解。

How do we prove the world is an illusion? A hundred years ago, our ancestors relied entirely on logic to make deductions and come to a conclusion. Today, apart from logic, we can also rely on technology to substantiate the conclusion that all phenomena are ultimately empty.

如何证明这个世界是幻觉呢？一百年以前，我们的前辈纯粹是用逻辑去推理、判断，而得出结论的。现在，我们在逻辑推理的同时，也可以利用高科技的方法，以便更清楚地证明，唯幻论的结论是颠扑不破的，任何物质最后都可以分解到空。
