Buddhists philosophize that this whole universe is Māyā—illusion—covering reality. The question comes to mind: Is the Moon or Mars as solid as the Earth? Portugal and Spain are as solid as Mexico. Does one know, even if they have never set foot in those countries? Are there doubters that the Great Pyramids of Egypt exist, having never visited them? Personally, I have seen the Great Pyramids, in December of 1991!
