Letters of Sri Aurobindo
Volume I - Part 2
The difference between intuition and thought is very much like that between seeing a thing and badgering one’s brains to find out what the thing can possibly be like. Intuition is truth-sight. 
The thing seen may not be the truth? Well, in that case it will at least be one of its hundred tails or at least a hair from one of the tails. The very first step in the supramental change is to transform all operations of consciousness from the ordinary mental to the intuitive, only then is there any hope of proceeding farther,– not to, but towards the supramental.
