It recently dawned on me that the letters of the alphabet are “re-usable” a seemly unlimited number of times. That we can pull one “out of thin air” seemly anytime we want whether talking, writing or thinking. Thus no letter can ever have any real meaning since they are perfectly interchangeable. For example, I can use the letter “A” in CAR or in HAT and a million more times if I like, and it works perfectly every time! The benefit of seeing this is that you realize that if letters are inherently empty of meaning, then so must words be. And if words are empty of meaning, then so are the mind’s stories.
