Reason is learned from the ever changing world, but true knowledge comes from the essence of life.

Knowledge and heart quality must be developed together. ... Without a developed love quality, man is incapable of having that knowledge. There are fine lights and shades in one's life that cannot be perceived and fully understood without having touched the deeper side of life, which is the devotional side. The person who has never in his life been wholly grateful cannot know what it is. He who has not experienced humility in life does not know its beauty. The one who has not known gentleness or modesty cannot appreciate its beauty or recognize it. ... The heart must be open too. A very intellectual man went to Jami and asked him to take him as his pupil and give him initiation. Jami looked at him and said, 'Have you ever loved anybody?' This man said, 'No, I have not loved.' Then Jami said, 'Go and love first, then come to me and I will show you the way.'
Wisdom is that which is learned from within, and intellect is that which is acquired from without. The source of wisdom is above, the source of intellect is below. And therefore it is not the same method, it is not the same process one adopts in order to attain wisdom as that which one adopts in order to acquire intellect.
