Later buddhist have worked this all out. They simply teach that we have a distorted perception and wrong understandingo f the nature of the mind. This is caused by defilements.
Once defilements are all uprooted we develop a correct understanding of what mind really is. But people do not believe this, i notice. They do not seem to be open for the fact that they do not yet understand the nature of mind.
It is completely normal, i feel, that the texts sometimes speak about the mind in a way that aligns with are wrong understanding of mind, as conditioned, as a stream of vinnana, local, humane etc. Sometimes they do not.
