There is no identity that is separate from the thing itself. Confused we think there are two cars, the identity car and another thing/not-yet-car, whose identity the first car is. But there is only one thing, the identity itself, there is nothing corresponding to it, there is no second car. Same with regard to a person.
So what is the first car, or first person, actually?Shurangama Sutra
, Chapter 2:
"The Buddha told Manjushri and the great assembly, 'To the Tathagatas and the great Bodhisattvas of the ten directions, who dwell in this Samadhi, seeing and the conditions of seeing, as well as thoughts regarding seeing, are like flowers in space--fundamentally non-existent. This seeing and its conditions are originally the wonderful pure bright substance of Bodhi. How could one inquire into its existence or non-existence? Manjushri, I now ask you: Could there be another Manjushri besides you? Or would that Manjushri not be you?'
'No, Bhagavan: I would be the real Manjushri. There couldn't be any other Manjushri. Why not? If there were another one, there would be two Manjushris. But as it is now, I could not be that non-existent Manjushri. Actually, neither of the two concepts 'existent'or 'non-existent' applies.'
The Buddha said, 'That is how the basic substance of wonderful Bodhi is in terms of emptiness and mundane objects. They are basically misnomers for the wonderful brightness of unsurpassed Bodhi, the pure, perfect, true mind. Our misconception turns them into form and emptiness, as well as hearing and seeing.
They are like the second moon: does that moon exist or not? Manjushri, there is only one true moon. That leaves no room for questioning its existence or non-existence. Therefore, your current contemplating of the seeing and the mundane objects and the many observations that entails are all false thoughts. You cannot transcend existence and non-existence while caught up in them. Only the true essence, the wonderful enlightened bright nature is beyond pointing out or not pointing out.'"
The one true moon, car, person, etc. are all misnomers for the "wonderful brightness of unsurpassed Bodhi".
The first car, person, you are speaking about correspond also to that second moon. "Like flowers in space--fundamentally non-existent", yet therefore "actually neither of the two concepts 'existent' or 'non-existent' applies".
