The Right Mind is like water.
The Confused Mind is like ice.
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.
