“The Right Mind is the mind that does not remain in one place. It is the mind that stretches throughout the entire body and self.
“The Confused Mind is the mind that, thinking something over, congeals in one place.
“When the Right Mind congeals and settles in one place, it becomes what is called the Confused Mind. When the Right Mind is lost, it is lacking in function here and there. For this reason, it is important not to lose it.
“In not remaining in one place, the Right Mind is like water. The Confused Mind is like ice, and ice is unable to wash hands or head. When ice is melted, it becomes water and flows everywhere, and it can wash the hands, the feet, or anything else.
“If the mind congeals in one place and remains with one thing, it is like frozen water and is unable to be used freely: ice that can wash neither hands nor feet. When the mind is melted and is used like water, extending throughout the body, it can be sent wherever one wants to send it.
“This is the Right Mind.”
