"Intuition" had come to lose its pristine value for me. I cast about for a better one and found it in "insight." This term I assigned to the highest knowing-faculty of sages and was thus able to treat the term "intuition" as something inferior which was sometimes amazingly correct but not infrequently hopelessly wrong in its guidance, reports, or premonition. I further endeavoured to state what the old Asiatic sages had long ago stated, that it was possible to unfold a faculty of direct insight into the nature of the Overself, into the supreme reality of the universe, that this was the highest kind of intuition possible to man, and that it did not concern itself with lesser revelations, such as giving the name of a horse likely to win tomorrow's race, a revelation which the kind of intuition we hear so much about is sometimes able to do.
