Let's dissect this sentence.
1. There is no trying. There is doing, or not doing. Also doing well, doing badly, doing middiling.
2. Zen. It descends upon us. Like the rain, or like sun & moon beams. You can't conjure it up on demand.
3. Perfection? Ah, well, maybe a bit of a fool's paradise, a mythical chimera flashing just out of reach? Especailly in the human realm.
Being perfectly human would contain multitudes of contradiction, flaw, foible, nonsense.
Is the Universe perfect? Maybe. Since it contains everything. I mean who is big enough to challenge that idea or quibble?
A flower, a mosquito, a river, a star. Sure, glimpses of perfection, reflected in the human eye. That's as close as you can get.
