The illusory nature of the maya is not some hypothetical figment of someone's imagination. It is true.
The maya is an illusion, but, paradoxically, it is also reality. And we must function in it.
In fact, we can and do function of many different levels of reality at the same time, all of the time. And these levels are not isolated, one from another; they flow together, more like spectra.
On one level everything is paradoxical.
On one level, it's all a matter of probabilities.
I'll bet my eternal soul that these screwed-up guys are consumed by evil and will find no reward for their actions. In fact that bit about paradise and 72 virgins is a bad joke on them.
We will all face the judgment of God. That day will come. In fact, paradoxically, that day will come, and that day is already here. (Time is an illusion also. But don't throw away your watch; this is another paradox.)
As a Christian, I know that these terrorists are infidels who are guilty of terrible sin.
As a member of the human race, I know that they are disgusting, reprehensible, screwed-up loosers and that the world will be a better place when they are all dead. There is no excuse for their actions. They must be hunted down and killed or rendered powerless. And civilized people the world over must never forget the importance of eternal vigilance.
