How wrong can our perceptions be?

Apparently, very very wrong.

We just don't see reality as it is, as any Buddhist or other meditator would tell.

We make it up all the time.

A funny example, which admittedly has little to do with Buddhism and much to do with Gestalt, is the famous figure enclosed here (click on it to expand).

Are squares A and B of the same colour? Of course not: one is white and the other is grey. Well, one is dark grey and the other is light grey. In any case, it can't be the same colour. No way.

Until you have a better look, process the image with PhotoShop, or visit the web site below:

Don't trust your illusions!
