Recently I ran into a term I have not seen before, "Mahavakyas" which in the text I was reading loosely was translated as 'great thoughts'. I went to find these, all 108 of them, but was unable to find but a handful, and no guide towards where to find them all. I have not read the totality of the upanishads, but am lead to believe that they are there in them? As it happens there are 108 upanishads as well, so I had thought perhaps there was one revealed in each part of the text?

If anyone happens to have either a file listing them all, or knows something about where I might discern these, I would appreciate the information.
