The most glorious fruit of the tree of knowledge is this
exalted word: Of one tree are all ye the fruit, and of one bough the leaves.
Let not man glory in this that he loveth his country, let him rather glory in
this that he loveth his kind.
- Baha’u’llah (‘Tablets of Baha’u’llah revealed
after the Kitab-i-Aqdas’)
