We can see colour because the fruits, berries and vegetables that we evolved to eat are colourful. The fruits, berries and vegetables are colourful because we, and other animals, see in colour. All things exist in this inter-related way.
When we focus on our individual dramas and successes we forget that we only exist because everything else exists, that we are dependent on each other. Whatever position we hold in the company we work for, without every other person who works there, from the top to the bottom, we would not have a company to work for. The same could be said of our society, culture and human race.
This line of thinking could extend out to include everything in the universe, but for practical purposes it helps to think on a human level. In short, we have much to be grateful for and much work to do, as everyone else needs us as much as we need them. The challenge we have is to figure out what our part to play actually is. To have a purpose in life is to know where you fit and how you can be the best you that you can. This is how we serve each other.
