Choice

Basically, there are two meta-rules.

According to the first, if you follow the precepts – to the letter – you get ‘there’.
According to the second, avoiding the forbidden sets the stage for things going your way.

Unfortunately, things are not as simple as they look at first sight.
The first meta-rule deals with individuals. Getting ‘there’ is each individual’s job. They have to do what they are supposed to and failing to fulfill any item banishes the unworthy from the cherished ‘prize’.
The second one is even ‘trickier’. While its precepts must be followed, again, by the individual followers, the ‘spoils’ belong more to the community rather than to the individual. On top of that, they are not ‘certain’! Following the rule only ‘sets the stage’. Disobeying the rule makes it certain that the goal will never be reached while following it only ‘opens the door’. Makes it possible for each of the community members to search for their individual paths towards their particular goals.

Do I need to remember you that both these rules exist only in our heads?
As figments of our imaginations?
And that the difference between the two can be observed at the practical level?

The first rule can never be fulfilled. Nobody can follow it to its ultimate consequence. No matter how hard any of us might try. It would be like measuring with infinite precision. Something will always happen. Go wrong. Throw us back to where we have started.
The second one also leads to disappointment. Some members of the community will inevitably attempt to cut corners. Take the easy way out … Hence the rule needs policing. You’ve certainly witnessed at least on occasion when ‘bad (money) has driven out good’… at least temporarily! Furthermore, some members of the community – while faithfully sticking to the rule, will still fail to get ‘there’. Set their aims too high, didn’t have what it takes… or simply had lots and lots of bad luck! But regardless of the why’s, not getting there still generates disappointment. Usually directed at the rule… and creates a lot of doubt towards the weltanschauung based on the rule…

Which way out?
How to choose?

Would it be helpful to notice that, historically speaking, the communities which have followed the second rule, primum non nocere, have fared decently while those who had attempted to prescribe, and impose, a ‘recipe for happiness’ have invariably failed?
‘Don’t do anything, upon another, which you wouldn’t welcome when done upon you’ versus ‘treat all the others exactly as you would like to be treated yourself’?
