maybe Vivianne. ..and we can leave it at that?
Or we can continue this thread of your puzzle " what is spirit?" and we can discuss the angles and deeper meaning, and answer with philosophic answers/ questions and conclude there is no one answer to your question....and learning to say A B C D E is easy but to put letters together and make words out of them is highly complicated.
So if " spirit " exists how can the intellect reflect it in letters?
