SECRET CODE
A secret agent was sent to a warlike country to collect information. His
task was to determine the strength and the intentions of the enemy country.
A simple but effective method was used to send information back to his
superior officers. In seemingly innocent letters to his own country he
casually included pairs of numbers, such as five and twelve, and thirty-six
and eight. The received letters were quickly decoded.
How? The secret agent possessed a copy of a book which had sold millions of
copies around the world. He used it to send his messages back home. For
example, the numbers five and twelve indicated page five, twelfth word;
while thirty-six and eight meant page thirty-six, eighth word. Anyone
knowing the secret code could read the messages.
Esoteric information is available to all. However, individual effort must
be made to learn its secret code. Fortunately, the code is located where
every man can find it - within his own nature."
