Each and every religion on this planet knows endless repeating, chanting or listening to the verses will bring subjects to certain state of mind resulting it self in a self fulfilling prophecy, this can be successfully used both ways for negative or positive results all depends on the message in the verse.

In our modern world same system is used by advertising industry.

In this case I do not talk about ciggies, I'm talking about shit like this:
*Choose a fucking big television Choose washing machines, cars, compact disc players, and electrical tin openers. Choose good health, low cholesterol and dental insurance. Choose fixed-interest mortgage repayments. Choose a starter home. etc

OK that should be our "positive" mantra and now obscure "negative" mantric verse, read or repeat 20 times per day "Smoking Kills" for several years and you'll be for sure dead!

Song: Choose Life Lyrics

Choose life.
Choose a job.
Choose a career.
Choose a family,
Choose a fucking big television
Choose washing machines, cars,
compact disc players, and electrical tin openers.
Choose good health, low cholesterol
and dental insurance.
Choose fixed-interest mortgage repayments.
Choose a starter home.
Choose your friends.
Choose leisure wear and matching luggage.
Choose a three piece suite on hire purchase
in a range of fucking fabrics.
Choose DIY and wondering who you
are on a Sunday morning.
Choose sitting on that couch watching mind-numbing
sprit-crushing ga me shows
Stuffing fucking junk food into your mouth.
Choose rotting away at the end of it all,
pishing you last in a miserable home
Nothing more than an embarrassment to the selfish,
fucked-up brats
You have spawned to replace yourself.
Choose your future. Choose life.

Main tune from the movie Trainspotting
