great Lord Atisha said:
Inwardly, sweep away the impurities of the five poisons. Outwardly,
sweep away all foul dirt and filth. And between these two, sweep
away the intervening impurity of laziness and indifference. Sweep
away bad food: meat, garlic, onions, and alcohol. Rid yourself of
all nourishment that is unclean and inappropriate. Those of you
who live on alms and follow a specific time schedule for meals,
sweep away the impurity of eating at improper times.
