A type of Māṇḍalika Dosa (blemish incurred at the time eating meals),
which is indulged in by an ascetic (Muni) by condemning the tasteless food and its giver. It is called Dhūma because, on account of this blemish, the transgressor (monk) as if converts the fuel of conduct into smoke (dhūma)
nindan punaścāritrendhanaṃ dahan dhiimakaraṇād dhumo doṣaḥ.
