What is Buddhist reality? 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?
In the Buddhist context non self has a special meaning which is not worthy of identifying as self because it is not always pleasant, there is not permanent core, there is not internal or external (God) controller.

Also there is conventional and realities. As social conventions you will refer to someone as an entity. This is for the sake of communication.
