Then said Mahamati: Pray tell us, Blessed One, what is the nature of Self-realization by reason of which we shall be able to attain Transcendental Intelligence?
The Blessed One replied: Transcendental Intelligence rises when the intellectual-mind reaches its limit and, if things are to be realized in their true and essence nature, its processes of mentation, which are based on particularized ideas, discriminations and judgments, must be transcended by an appeal to some higher faculty of cognition, if there be such a higher faculty. There is such a faculty in the intuitive-mind (Manas), which as we have seen is the link between the intellectual-mind and Universal Mind. While it is not an individualized organ like the intellectual-mind, it has that which is much better direct dependence upon Universal Mind. While intuition, does not give information that can be analyzed and discriminated, it gives that which is far superior, self-realization through identification.
