Reason must no longer be the summit and the master. For a very long time in life, until one possesses anything resembling knowledge, it is indispensable that reason be the master, otherwise one is the plaything of one’s impulses, one’s fancies, one’s more or less disordered emotional imaginings, and one is in danger of being very far removed not merely from wisdom but even from the knowledge needed for conducting oneself acceptably.
But when one has managed to control all the lower parts of the being with the help of reason, which is the apex of ordinary human intelligence, then if one wants to go beyond this point, if one wants to liberate oneself from ordinary life, from ordinary thought, from the ordinary vision of things, one must, if I may say so, stand upon the head of reason, not trampling it down disdainfully, but using it as a stepping stone to something higher, something beyond it, to attain to something which concerns itself very little with the decrees of reason; something which can allow itself to be irrational because it is a higher irrationality, with a higher light; something which is beyond ordinary knowledge and which receives its inspirations from above, from high above, from the divine Wisdom.
That is what this means. As for the knowledge of which Sri Aurobindo speaks here, it is ordinary knowledge, it is not Knowledge by identity; it is knowledge that can be acquired by the intellect through thought, through ordinary means. But once again-and in any case we shall have occasion to return to this when we study the next aphorism-do not be in a hurry to abandon reason in the conviction that you will immediately attain to Wisdom, because you must be ready for Wisdom; otherwise, by abandoning reason, you run a great risk of falling into unreason, which is rather dangerous.
