Regarding Lals reply I would add: There is a moment when one on the path can see that even having an opinion or tending to think and ponder about worldly things is already a danger and ditthi. If harmful or not helpful thinking is involved one is acting with lobha, dosa, moha. Normal people always tend to value mundane issues highly. They cannot see the futility in it. These worldly activities will bind one to this world. The mind will get agitated and thus pulled away from Nibbana. The peace of mind is disturbed. Of course some activities are still necessary to fulfill certain tasks and responsibilities.

But when, for one who speaks of what has been seen, unskillful mental qualities decrease and skillful mental qualities increase, then that sort of thing should be spoken about. …”
