So, a crystal ball for divination may have a window into another dimension. That's why crystal balls are used for fortune-telling, not by accident. Old, decorated wine glasses with a round crystal in the stem could, in some sense, be a window to another dimension. The domes of temples and the tops of Orthodox churches are windows to another dimension when people pray there. A ball used to play football, basketball or tennis is a window to another dimension, hence the popularity and magnetism of such sports. A geographical globe or glowing planet in the room is a window to another dimension. Our eyes and heads are a window to another dimension. Some sexual body parts are spherical too. Clocks and light bulbs are windows to another dimension. Microphones and speakers could be a window to another dimension. Am I exaggerating a bit? Finally, explosives, New Year fireworks, and war explosions are, for a moment, windows to another dimension. And for a longer time in the event of a nuclear explosion. (Besides, the topic of karma and destruction appeared in some channeling, whether fake or not; the first one I came across was presented as a "conversation with an alien": it must have been created on the basis of some books, maybe RA material). Everything in space forms a sphere spontaneously, if only possible. So everything tends to be a window to another dimension. Black holes seem spherical. We should probably remember that atomic particles are also spherical from some point of view. I'm using the term 'dimension' generally as a placeholder term for possible concepts. (Anti-universe, density, dimension, time-space, whatever is possible)
