The beauty we should strive to maintain is the one that comes from being a gentle, loving, kind, merciful, forgiving, compassionate, selfless, and strong person who is not misdirected or shipwrecked by the winds and rains of circumstance and happenstance. Therefore, it is very important that we must develop the important elements of who we are such as our integrity and fortitude, and our inner security and faith.
The reality is that true beauty in an individual has no tangible measure- it does not require wealth, power, or fame, nor does it involve make-up, expensive clothes, or any other form of vanity- it simply requires strong character. And once we have that, others will be able to look to us as a source of guidance, strength, and inspiration in their own lives.
However, guard your beauty diligently, so that no ones ugliness rubs off on you.
