But please explain me, what is the spiritual or moral significance for the small children of the Treat or Trick routine? What idea do they get from it?

There is no "spiritual or moral significance." The idea children get is that they get to dress up once a year and get goodies. That's all.

So what the Treat or Trick routine means? I guess if you do not make a sacrifice to the spirits they will do damage to you.
