We can be the biggest somebody in the world when we have no attachment, but we have to start from somewhere, we can’t start out being nobody. The force of “somebody-ness” that develops the survival mechanisms (social, physical, etc.) is our starting point. It is in the freedom of non-clinging to models about self and other that you begin to tune to and hear the way of things, called the Dao or the Divine Law.
When you respect that tuning in yourself, actions that flow from you start to become dharmic. They are acts that release beings from suffering and do not perpetuate the illusion of separate self.
