142857 ... A MAGIC NUMBER?

Add 142857 to itself.
Look at closely at the individual numbers in the sum.
Now add the original number to this sum,
and again to each subsequent sum,
noting each time the arrangement
or pattern in each string of numbers.
When you add 142857 the seventh time,
something so mind-blowing will happen that ...
(I take not credit in this "Mathematical Beauty".
This is taken from "The St. Anthony Messenger".)
