It isn't in the skin, the face or the body which makes a person's heart melt. Although physicality can drive one into madness, it does not stand the test of your time. If one becomes determined by their physicality when it is rich in youth. The self will not ferment with wisdom but instead acquire a brash feeling of entitlement.
Physical beauty is primarily based on aspect ratios, symmetry, and associations. Our physical associations in many cases are perpetuated through media but are also heavily influenced through personal activities. Infatuation perpetuates the delusional mind every step through a maze. It will only find the truth there waiting to enslave the reactive mind.
True beauty will out-sell any pageant queen. The curse of physical beauty is within being bought and sold at auction through the highest bidder. This bidder quite often paying large sums of cash to have a delusional ego fed all the time. A charlatan enslaving physical beauty as a symbol of status and letting it fall away as depreciation sets in.
What we truly find beautiful is often portrayed in literature, the main component being kindness and sacrifice. It had not been Snow White's cartoon body and face that made millions anticipate her triumph at the end of the story. Nor was it the symmetry of Cinderella's animated brow. Often the hero is masked to be able to display the otherwise hidden altruistic truth within.
Nobody records into history the symmetry of a face. Nature by itself displays physicality's expendability through the process of getting older.
If you want to be beautiful you must condition yourself to sacrifice without the expectation of reward. Don't become an animal that performs tricks for treats. One can rarely observe his/her own poor acting skills.
If you practice sacrifice without the expectation of reward, it will become part of your nature. This can be a very difficult path. You can't command the rewards from true beauty. The rewards are often times shared rather than hoarded.
Practice compassion and someone might catch you by accident when you least expect it. You shouldn't be caught as the good-deed-doer, others knows you are looking for a trade.
