Yuka, I think that you mean you want an example of what it means to "Take the most beautiful part of you that you've never met." If this is what you mean, you need to write an essay to describe, in loving terms like you would say to a friend or lover, a part of yourself that you don't care for, such as maybe you don't like your teeth because they are crooked or maybe you think your waist is too big or maybe you don't like that your memory is too short. Then describe what you DO like about that part of you.

I'm inclined to say that it should actually be "Take the most beautiful part of *youself*" . Anyway the wording is a bit .... oblique and internally inconsistent. I think whoever concocted it was trying to make it sound deep but just managed weird. I'd be inclined to rephrase it as. "Take that aspect of yourself that you turn away from and deny and embrace it as you would a dear friend or lover." As for an inspiration for an essay, I'm not much help I fear. I suspect the idea is to find an aspect of yourself that you don't like and then over the course of the essay find a way to come to terms with it or become accepting of it. This could be a physical, emotional, or physiological characteristic. You could for example have some fun with it. Say you were ashamed of your phobia of spiders, then you could accept that phobia and become proud of it over the course of the essay.

It's an instruction for my essay, but I don't know if I understand it, so I wanted to know the meaning (example) of "take the most beautiful ------or lover" . For example...?
