Which of the following statements is correct in regard to the rules that Bhikkhus had to follow?

a- Under no condition, a Bhikkhu was allowed to accept more than 3 bowls of cooked grain meal or cakes.
b- When a new blanket has been made by a Bhikkhu, it is to be kept for at least six years.

Only statement b is correct.

In case a bhikkhu arriving at a family residence is presented with cakes or cooked grain meal, he may accept two or three bowlfuls if he so desires.  If he should accept more than that, it is to be confessed. Having done that, he has to share them among the BHIKKHUS.
