The doctrines of emptiness and selflessness do not imply the non-existence of things. Things do exist. When we say that all phenomena are void of self-existence, it does not mean that we are advocating non-existence, that we are repudiating that things exist. Then what is it we are negating? We are negating, or denying, that anything exists from its own side without depending on other things. Hence, it is because things depend for their existence upon other causes and conditions that they are said to lack independent self-existence.
