The prime universal law is the Law of Attraction, as described by Abraham-Hicks. I'd describe it as: what you dwell on, you get. From that come a couple more and our happiness depends on lining up with these laws--especially the Law of Attraction. Our happiness, and our prosperity.
The world is not respectable; it is mortal, tormented, confused, deluded forever; but it is shot through with beauty, with love, with glints of courage and laughter; and in these, the spirit blooms timidly, and struggles to the light amid the thorns. ~George Santayana
"For Attractive lips, speak words of kindness.
For lovely eyes, seek out the good in people.
For a slim figure, share your food with the hungry.
For beautiful hair, let a child run their fingers through it once a day.
For poise, walk with the knowledge that you never walk alone.
People, more than things, have to be restored, renewed, revived, reclaimed, and redeemed. Remember, if you ever need a helping hand, you will find one at the end of each of your arms.
As you grow older, you will discover that you have two hands, one for helping yourself and the other for helping others."
~Audrey Hepburn
Ms Hepburn's grace comes from what Abraham (through Ester Hicks) might call some extreme contrast.
She had seen very difficult things and wonderful things in her very rich life. Here's an interview with Phil Donahue. It sheds some light on what stood behind of Hepburn's simultaneous depth and lightness of being.
