Hi jason, all,
however the rule came about, it works.
I mean, ime, if I eat the evening meal, then try to sit meditation that night, the mind is shabby at best, or dull at worst. But - if I have kept to the 'eight-precepter rule' and ate only breakfast and lunch, and nothing after,
so that the stomach is completely empty by sundown - then, the mind is clearer, brighter, and is
capable of sitting meditation properly.
Two other points. 1. It makes sense to have the biggest meal at lunch time, when the digestive power is strongest. 2. It is not as tough as it sounds, if you take advantage of what the Buddha allowed after mid-day such as (no pulp - filtered) juices of fruits or juices of leaves, herbal teas (there are some that allay hunger pangs), a few allowable candies if you feel desperate for the feeling of eating something...anyway, I am experimenting with gradually moving closer to this regime and so far, I just keep feeling better and better, physically and mentally. But, the first couple of days was tough,
I must say. One has to get used to it.
One last thing: we really do not need three main meals a day, unless we are doing heavy physical labour as our main occupation, imo. Most of us in modern society could easily forgo the evening meal, and not starve as a result. For me, the difficulty of the first few days was all this emotional stuff coming up, that would normally have been supressed by stuffing down some food. That seems to have passed now. I will see how it goes, but I am warming to this routine, and recommend it, however: if you are sugar-sensitive, hyper or hypo glycemic, or diabetic, please consult medical advice first...just to be safe.
