520 is the number for miracle to happen. Whenever you have unresolved problem or when you need transformation immediately, 520 will work. For example, after the exam is over 520 will work, as the student needs a miracle, may be in the form of getting an engineering seat.

When there is a problem you will break your head. At that time switch word FIND will not work, but REACH will, as the solution is within you. When your mind is completely confused whether to do this or do that, then only REACH will work.
