We will begin with a definition of wisdom. Like the other Rabbis of his day, Rabbi Haninah was an adept of the mystical schools of Torah. Judging from his actions, he was a master of accomplishment equaled by few others. Apparently, he succeeded in ascending to the heights of spiritual accomplishments. This is the level of Keter, the crown, the symbol of the Divine Will.
Wisdom is the second of the ten sefirotic emanations.
Although referred to above as an intellectual accomplishment, wisdom is not acquired through academic study. Actually, wisdom can only be acquired as a gift from G-d. While we might do many things to achieve it, unless G-d gives us wisdom as a gift, all our efforts to acquire it will be in vain. Wisdom is a glimpse of the Divine Will, the Keter. Wisdom as experienced by us is those aspects of thought that come to us independently.
