Wisdom is like a baobab tree; no one individual can embrace it.
What it means
A baobab is too wide for one pair of arms to reach around. Wisdom is the same: too vast for anyone to claim they have mastered it, however learned they are.

The source explains it: one person cannot collect them all, cannot analyze them all, cannot put them all into their context and cannot use them all. The wording of the meaning is ours.
