What is the mind? Listener question

Just reflecting on energy. More specifically the amount of energy that as stated by Adyashanti it takes to maintain those illusory beliefs,the false narrative ,the conditioning ,the projection of the I at the centre of a created reality as opposed to being alive, in flow, whole, true and home. My question is are we saying that we do not have a mind i.e it is a  maladaptive programme running on false data. Or that the mind does exist but that inner engineering is required to make it work in service of us as human beings. Hope this makes sense ?
