How do I practice ' see things as they are'?

Further to the answers to this question , I want to understand what literally is 'see things as they are' or as the sutta states, *Yathā-bhūta-ñāna-dassana *. My questions are, 1. I understand that if I am looking at a beautiful woman, I am obviously not seeing as she is, but what when I am looking at a clear blue sky, not clouded by ignorance, lust, and greed, am I seeing things as they are? Or I should necessarily have to have insight into *Three marks of existencece* ? Can I see things as they are without Enlightenment? 2. If so, can only an enlightened being see things as they are? 3. Sometimes when we look at a flower we can see something transcendental, something which is greater than the sum of the parts. (Not a concept from Buddhism) but some people have an aura around them, even the Buddha in pictures is shown with an aura around His head. So does seeing this metaphysical reality constitute seeing thins as they are?
