I’ve always found Celtic knots attractive. I think they are both beautiful and fantastic symbols of important characteristics of reality – the indivisible inter-connectedness of everything, and the dynamic, flowing qualities of Nature.
Alan Watts, that great teacher of Zen principles, talks about the reality of inter-connectedness in one of his essays. He says -
interdependence and virtual identity with all other forms of life which the divisive and emboxing methods of our current way of thought prevent us from experiencing……….The so–called physical world and the so–called human body are a single process, differentiated only as the heart from the lungs or the head from the feet………..our intellectual and scientific “establishment” is, in general, still spellbound by the myth that human intelligence and feeling are a fluke of chance in an entirely mechanical and stupid universe—as if figs would grow on thistles or grapes on thorns………wouldn’t it be more reasonable to see the entire scheme of things as continuous with our own consciousness and the marvelous neural organization which, shall we say, sponsors it?
