universal laws are just
that, a finite body is
an inherent obstacle, he
doubts the implied outcome

I am not sure I fully understand the question, but here is my take on what I think you are asking.

The laws were put in place for a reason. An entity that is infinite in power and wisdom does not need nor obey any rules. The Infinite decided to become finite to experience limitation, because there was no other game left to play... I mean what can be a more exciting game for the Infinite than the game of losing itself in the Limited and the Finite - and then eventually finding its way back?

The laws are in place to aid the Finite and the Limited. They need the laws and the rules and the frameworks - just to save them from having to create order from scratch, which they are not capable of doing in the first place - because they are finite and limited.

Man often put them self under some law that does not serve or help them. also man is always trying to define what he see or understand by law. look at physician and scientific people. always trying to calculate stuff.

right now in quantic physic it does not work any more. their law does not work in that new quantic universe.

maybe it is because of their monkey brain. that see stuff as things. many still think that they are monkey any way. and that they look at banana.

yet they look at sub molecule and energy. at stuff so small that it is another realm.

to give you example it is smaller then atoms. and each atom that compose solid matter in this world you could put house in between.

they say we do not understand by what law it is working when we try to trap something to measure it; it is fighting back and brake out of the constrain.

it never occurred to them that this thing might be living or that the force that they are trying to apply to it is making it fight in opposition to them.

they say about the time that stuff that move away at great distance or come back is not in the same time slice of now. yet they do not understand that what they observe when they are not observing it; it is moving.

yet they are looking in a very smaller universe on the scale of things. it never occurred to them that you can have living things in that universe. or that some stuff in that smaller universe might be galaxies view from the scale of something in it.

we human in this world even when we are not moving are in fact moving since the planet rotate on it self it also rotate around the sun and the galaxies that we are in is also moving in this expanding universe.

so on the scale of thing if we would put our self as one of those living thing in it. and we would see something very huge so huge that from our point of view it is outside of our universe trying to trap us of course we would try to escape by any means necessary.

if you can understand this. then would you say by what law is that working? we do not get the same result at each test we are doing we have different result and cannot put our finger on what law it is working by!

and if it is not alive. then it is just human clumsiness. with very huge finger and instrument trying to do stuff on the very small scale. just like a scientist studying dust particle. that would sneeze on it and the dust would move but he would never realize that he sneeze on it and is the cause of the effect he made on is experiment and would observe it and say the observer is affecting the result. of course the observer affect the observed.

you can see it in human interaction in this world is it working by any law?

if you where alien to this world and looking at someone a human being in this world and trying to find by what law does this thing work? we will do test on it to find out!

and after some test say we do not understand by what law it work when we try to measure it; it fight back. also we never get the same result some time it escape to the left sometime to the right some time it goes up or down or it disappear or disembody.

man in this world make law and constrain them self by those law. often they need to make some exception or change some law because some law does not apply any more to some situation or when those law where created with good intention they did not see the wrong that they could do or that those law would cause them problem in the long run.

also about law in this world people have to comply to law of the country law of the state law of the city law in the work place that they work.

and you want to make your self personal law?

ask your self this what are the two greatest law?

1.Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul, and with thy whole mind, and with thy whole strength; 2.Thou shalt love thy neighbor as thyself.

try starting with those two law.

and if you want to constrain your self to other law or put your self in to bondage it is your choice.

"One can't enter a strong person's house and take it by force without tying his hands. Then one can loot his house."

so be wise and make the proper choice so that you do not fall in bondage.

the truth will set you free.

man makes a lot of law for every thing. and try to follow it to the letter often making problem for them self and other. yet if they would have a pure heart, with justice , mercy , and good faith. they would see when the law is failing and would know what to do. since they would be just between them self and other. they would have mercy for one and other. and they would have good faith for one another.

there is the letter of the law and the heart of the law.

what is the heart of the law justice, mercy , good faith.

Let there be light, be the light that you can be, experience and enjoy.

"Can we create our own universal laws that work best for us?"

Yes, we refer to them as beliefs.

And No, because if they only work "best for us", then they would not be universal.
