There is no duality there can not be this is not something i have intelectualized it is somthing that my being just knows. The rock is real. It is also and illusion why because all things are non dual.
You left out the teaching and all things are NOT non-dual. Don't forget this or you fall into the mind trap of nothingness which is contrary to the Buddha's teaching. Remember, emptiness is also form.
Now Because the self is an illusion no self exists but because illusion and untimate reality (samasara and nirvana) are one and the same the illusion is reality. Hence the illusion of the rock made the illusion of your death by the reality of your bloody head.
This isn't completely accurate. The Buddha never said there is no self. He said there is no self that is a permanent entity. There is a self, it just constantly changes. He called it illusory because it changes constantly how can you label something that constantly changes?
There is no mind and there is no rock and there is no death because there is no you. And all of these concepts are truely real in every sense because of the fact that all the universe and every phenomena in it is non-dual illusory-ultimate reality. So you can argue with me that the rock is unreal or you can accept that your bloody head is bilss and pain which do you choose.
Once again, not entirely accurate. The rock does exist, however it does not remain a rock for ever, this is why it is called non-existent. I know that sounds confusing but things exist, things also do not exist, but they also at the same time do not not exist.
A cup is only a cup until you break it. The cup was once some clay. The clay was once some plant matter. The plant matter was once some minerals in the soil. The minerals in the soil were once smaller particles. Those smaller particles were once non-particles. How far do you need to go before the cup ceases being a cup?
All things are like this.
