And again what fire there is in the hall (sabhâ), that is the same as Anasnat Sâṅgamana: Anasvat (not eating) it is for the reason that people approach it before they eat. And that (place) where they throw the ashes they remove (from the fireplaces) is the same as Asat Pâmsava. And whosoever knows this, thus gains all those worlds, traverses all those worlds, thinking, 'In me those gods reside.'
