Einstein represents the opposite of intuition. There was no mystical hidden knowledge in his work. He attacked deep questions with logic and discovered new answers through reason and mathematical rigor.
Einstein's work is documented, through papers and letters, so that anyone can consciously go through the steps he did to get the same answer in the methodical thought process he used to reach his revolutionary conclusions.
And Einstein's revolution was to break intuition. Time dilation is not intuitive nor is quantized energy. These are thing you reach through math and rigorous logic, not through intuition.
This is why it is so frustrating when the intuition cult, which wants easy answers to come to you without reason, hard work or mathematical rigor hijacks Einstein's legacy.
No one can find any record of where Einstein said this bogus quote about the "intuitive mind" (real quotes have a source and a history). It is not Einstein's style (he didn't use the word "sacred" like that). Obviously someone ascribed it to Einstein because no one would take it seriously if they hadn't.
And there is no record of this quote from before 1976 when it was apparently invented.
