Osho on Power

"Power is the worst drug that people can become addicted to; it should be given, but in very small doses and not for a long time." - Osho

When you train people in Martial Arts, you are essentially training them to be powerful, you must be careful of who you teach and how you teach, if you train many people to become addicted to power, you will be creating a great disservice to society.  You can be responsible for training a whole nation of bullies who are addicted to abusing their powers over those whom are weaker.
