Everything wrong with not getting to grips with the intellect. The intellect is merely the servant of wisdom. Whatever is realised with wisdom is communicated via the intellect.

You see, there is an inherently violent Hindu Guru tradition exemplified by Hindu Gurus such as KM & UG; always violently scolding & putting down others; always treating others as though they are not practising & should be practising. This violent tradition of Self & Conceit is not Buddhism. Those that practise this Exalting Oneself & Disparaging Others are not practising the Dhamma (MN 139). Its best to merely discuss the teachings & doctrines. If you tell someone to "Taste the Honey", this is the presumption they have not tasted the honey. Presumption is conceit & not dhamma.
