I get what is being referred to, but if you are implying that buddhism teaches everything is an illusion, the Buddha himself specifically warned his followers away from nihilism and solipsism.
Your everyday conventional wisdom is not negated by buddhism.
For example, buddhist people use the word 'I' all the time ("Let me show you the path on which there is no coming and going."), despite trying to realise the doctrine of 'no self" in their practise.
The doctrines attempt to eliminate suffering, proceeding from the coarsest levels down to more and more subtle forms of suffering.
The delusion the monk is suffering from here, can only become uncovered after much work has been done clearing the way first.
