Our inner beauty is self-appreciation—that leads to effortless confidence. And just like our fascination and appreciation of beauty in nature (forests, mountains, lakes, sunsets etc), we do so because they are natural. Its beauty is lost when we try to artificially beautify it. But when we learn from its organic wisdom, to go with its nature, the beauty is preserved.
From a human perspective, we do need to take care of our personal hygiene, and wear appropriate clothings for social engagements. But more so, we need to focus on our diet, rest, developing our strengths & transforming our weaknesses – to bring out a better version of ourselves into the world.
