You have been centered hundreds of times in your life. It could have been when you were playing as a child, or joyfully involved in a project in business or school, a sporting event, a relationship, etc. You can learn to choose centering at any time so that you can be powerful and effective in pressure situations. This is accomplished through daily practice. Creating an environment where you can 'take five' and breathe deeply to regain your groundedness and stability at times during the day is an excellent first step.
True power is energy flowing freely toward a purpose.
This contradicts the traditional perceptions of strength as toughness and rigidity. True power requires an absence of tension. If you have an argument and you walk out of the room, even though you separate physically, the energy of the relationship continues. Accepting your connectedness is an important step in solving problems. When you learn to extend ki or energy, you are growing rather than contracting in relationship.
