In philosophical teachings which form foundation for Ninja Warrior's lifeways, there is a principle known as 'law of interdependence.' This so-called 'law' is not a must-do rule which one must follow, nor is it to be confused with dependence or co-dependence as it is seen today where one or more individuals who cannot or choose not to provide for themselves, lean on and 'depend' on work and resources of another for fulfillment of their needs. Rather, law of interdependence is something that is to be recognized as a basic 'truth' in world. Much like law of gravity or cause and effect, it is something that is 'going-on,' always, regardless of whether we 'believe' in it or not. In fact, contrary to our need to believe that we are what we are, this principle in action shows us that we are more like others than we know.
Unlike law of gravity, however, which is difficult to understand and explain; interdependence is relatively easy to explain. Let's use a simple analogy to understand this 'goings-on.' We'll use something simple, like a Whopper. No, I'm not being paid to endorse a food franchise and you can feel free to substitute this item for any of a thousand others. But, for our purposes, it will do.
Now, most people would agree to connection between themselves and all of individuals working in restaurant at moment you visited and placed your order for sandwich. Someone took your order; another was busy making product; and others made sure it found its way to a tray or bag and ultimately into your hand. In this simple view, there is an interdependent connection between you - person who 'wants' sandwich, and those who are making sure that you get it.
Of course, seen from viewpoint of any worker, they are mutually dependent on you, and many others throughout a day, wanting and willing to pay for a sandwich so that they can get a paycheck at end of week. For you: no restaurant - no sandwich. For them: no customers, no restaurant, no paycheck.
But, in words of enigmatic guru "Morphius" from popular movie, "The Matrix", if you really want to see "how deep rabbit hole goes," we can look much more closely at that simple sandwich.
Let's begin with wrapper. It wasn't made there at restaurant. It was delivered, probably by truck. Which means what? Well, where do you want to start? Driver? Truck dealership who sold it to Burger King? Truck manufacturer? Trailer manufacturer? Get idea?
For now, let's stay with driver and truck remaining associated with restaurant. But, already we're talking about more than just employees working in restaurant, aren't we. Many, if not all of them have families which will benefit from their paycheck in some way just as company is benefiting from their desire or willingness to do job they're doing.
The wrapper itself is paper which now extends our connection to people working in logging and paper production industries and their families. The ink does same along those lines; and so on throughout rest of parts of sandwich like burger, vegetables, and so on.
