How can we keep what we do not remember?  Most of us do not even know the Ten Commandments.  The Hebrew letters solve that problem.  The picture of each of the first ten letters help you never forget the commandments.

Not only do the letters make a perfect memory system, but they also add some insight to the reason we need to keep the commandment.
