Not only is the kitchen a great place to relax because it has food, but it's also a place of quite introspection. I usually go there, even when I'm not hungry, just to walk around and look out the window. I think. It's a place where I can let all my thoughts come together and I can sort things out.
The kitchen can also be a very social place, where everyone in the house gathers to make small talk and joke around. You feel connected with others, and it can make you realize that a lot of what you worry about, really doesn't matter. Friends and family are one of the most important things in your life.
But perhaps one the most important reason that I think the kitchen is a relaxing place, is because for me it represents a place of symbolic, spiritual cleansing. The kitchen is usually dirty, and every few days I have to clean it. When that happens, I view the event as a representation of my own inner, spiritual state. When the kitchen is out of order, my life is chaotic. When the kitchen is clean, my life has order. In cleaning the kitchen, I once again bring order into my life.
In conclusion, I believe that the kitchen is the most relaxing place I go. Everyone needs a place to relax. Where is your place?
