You can only begin where you are, but wherever you begin becomes the place where you are. So you can always begin, and this is rebirth.
A method actor tries to be, on screen, the living accumulation of everything his character was doing, all those decades, before being ‘reborn’, in the opening scene of the movie. Every story has a back-story. The back-story has to die, or there can be no story. The back-story dies, and is reborn as the story itself.
There is always so much weight of back-story that, in a sense, it is more of a story than the real story. The real story is already dead. That is true of every story. But the real story is also now, vitally so, or tomorrow’s real story cannot be born, will be born with severe disabilities, due to malnutrition by its own back-story.
Every story carries a double burden; the weight of its back-story, and the weight of its pregnancy. It is gravid with its own death, getting ready to give birth to the real story all over again.
So giving birth means giving death. Rebirth means spontaneously accomplishing the preceding death. That means beginning must always be the main practice.
