We often talk about spirit and matter as if they were two seperate things. At first glance, this seems to be true. When we consider a stone and when we consider a thought, we see that they are totally different. One is very solid matter and the other is no matter at all. A stone can be weighed, broken, thrown, and used as building materials. But wait… Thoughts can also be weighed, broken, thrown, and used as building materials. As for thought in terms of weight, there is a study showing that the spirit has a weight. People weighed before and after their death are slightly different in weight. The change in weight seems to be 21 grams. That’s about 21 paperclips or nine dimes. Also when we are worried we say something is « heavy on my mind ». Thoughts are broken in times we say that we have lost our train of thought. Forgetfulness or trying to remember a name, for example, are also times when a thought is broken. Thoughts are thrown when we flirt or shoot someone an angry look or and evil eye. Parents and lovers thrown thoughts all day. Thoughts are building materials when we are « brainstorming ». In groups, when we look for a new idea or a solution to a problem, thoughts are built on top of each other. In these brainstorming meetings, thoughts either construct themselves into something usable or they tumble and fall. Look at how many « Thought blocks » were used to build a skyscraper.
