One day a child comes home with a black eye from a fight at school. When his mom asks if he counted to 10 before fighting, he says "Yes, but the other kid's mom asked him to count to 5."
But this technique works. It works because consciousness heals. When we bring consciousness to action, we automatically start acting in our own interest. If we are conscious while driving, we tend to drive safely. If we are conscious about our calculations, we score better marks in Math. If we are conscious during interpersonal interactions, we are better at detecting whether we are successful with the other person.
When people told us to count to 10, they knew that the gaps between the counts contained consciousness ... our best weapon against our own unwanted behaviour. Consciousness or awareness can be achieved by regular meditation. Keep Meditating
