The following answers are just my opinions, I do not claim emperical knowledge nor do I claim to be perfect.
":?: My questions is this - is it ethical to accept gifts from the universe, or to create the life you want, without doing it in a way that current society is accepting? "
"For example, is it ethical to use magic to produce food? ':)" This is a trick question, right? Yes.
"Is it ethical to be an artist and not share your paintings, music, or pottery with the world?
" Yes, the artists I know put themselves into thier creation, and to force them to share themselves with the world when they aren't ready would be the same as a man walking up to a beautiful woman and saying "you have a beautiful body, it is unethical for you to not share it with me, your place or mine?
"Is it ethical to shine brightly in the world, yet not live the "commoners" life?" How is shining brightly hurting others? Living large has its own life lessons. Not sure I understand this question.
"Is it ethical to transform guilt on the planet and not tell anyone?"
No, you would be denying people thier life lessons.
"Is it ethical to see the knot of lies that holds financial institues together and unravel it shamanically, even if it will make millions, possibly billions of humans unhappy or even kill them with the change?
" To force others to live thier life according to your moral values is self righteous, to force millions is also megalomaniac.
"Is it ethical to dream a mighty dream and live that dream, even if it is not what you were taught would happen?" Another trick question? I think it our duty to ourselves to question what we have been taught.
"Even if it changes the world so much, that societies around the world are affected in ways they may not like?" Now we are getting megalomaniac again.
"Even if it changes the world so much, that societies around the world are affected in ways they absolutely love and embrace in ecstacy?" See above, add delusional.
"Even if living your dream doesn't affect a thing around you in a way anyone seems to notice?" Unless your dream is to a hermit, I'm sure people will at least notice you are happy.
"Is it ethical to be in tune with Magic so much that experiences on this plaent just manifest without effort - and you live the life you really want? and live that life in the way you want?" If you have been given that gift, then you have it for a reason.
"Please let me know how you see this? What do you see being the consequences of living a magical life?
I think the hardest part of our path is to remember that not everyone is on the same level, and that the pain and suffering we see often has a life lesson attached that people need to learn in order to grow. Knowing when to change the world, and when to let it alone can be tricky.
