Many parents complain that food should not be taken with more delay. This may be told as of a reason that "annam parabrahma swaroopam" and delaying the food by engaging in other activities is like insulting goddess Annapurna. Also say that while consuming food, one should not involve in any other activities.
Delay in this question refers to an assumption that the food is already served and the individual although arrived to eat, letting the food to wait in plate without consuming it.
My question is, are there any references which provide explicitly about that same.
