The Cube is an imitation of life itself - or even an improvement on life.
The problems of puzzles are very near the problems of life.
A good puzzle, it's a fair thing. Nobody is lying. It's very clear, and the problem depends just on you.
Usually we are saying only part of the truth.
The Cube can seem alive as it heats up in your hand. The fact that each face of the Cube is made of three layers of three blocks has an important meaning.
Like after a nice walk when you have seen many lovely sights you decide to go home, after a while I decided it was time to go home, let us put the cubes back in order. And it was at that moment that I came face to face with the Big Challenge: What is the way home?
