To me, Life is one big lens. And what I mean is that it's all about understanding that the view (or belief, thought, opinion, etc) that we have about someone or something is just one way to look at it (to put it simply). So, for example, if we say that the sun rises in the east and sets in the west, this would be correct as per the perspective from here on Earth. But what if we look at that same idea from the perspective of the Sun. It would appear that the Earth is circling the sun.
Or if you were driving in your car and you saw a homeless person begging for change, what would you see? Would you be annoyed at the hassle? Or could you see a different perspective? Perhaps he is testing your compassion?
Or the job that you got fired from that was initially devastating, actually ended up being the very thing you needed to find your dream job in another city.
We have to know that we have the power to shift the lens of perspective instantly. And when we are able to do this, we are given more information, more awareness, and more faith to make decisions that would affect not just ourselves but whoever else our decision would directly or indirectly affect. In other words, you will make wise decisions.
Remember, everything is about balance. Perspective is just another word for how we see things. And truly, there are an infinite amount of ways to see things.
