What is Buddhist reality?

Question: 

If the Buddha said that ultimate reality is really non-self (anatman), or empty of inherent existence (sunya), then why did he bother to talk about human beings and other “provisional” things?

Answer:

Your question mean nothing in present, in the past, and in the future.

But buddha mean present thing is nothing in the past, and present thing is nothing in the future.

Ultimate realities of human being are causes and effects.

Nibbana ultimate reality is perfect finished of causes and effects.

Anatta is uncontrollable to being or nothing. There are just causes arising to make effects. And effects vanishing because of causes vanishing. No self, no atta.

Ultimate realities all is anatta. Ultimate realities of human being is present, past (present of it's past) and future (present of it's future). They are present because of their causes arising. They are past because of their causes vanishing. They are future because of their causes still possible to arise.

Nibbana ultimate reality is no time because it has not any cause, so no any effect, too.
