Strain every nerve to acquire both inner and outer
perfections, for the fruit of the human tree hath ever been and will ever be
perfections both within and without. It is not desirable that a man be left
without knowledge or skills, for he is then but a barren tree. Then, so much as
capacity and capability allow, ye needs must deck the tree of being with fruits
such as knowledge, wisdom, spiritual perception and eloquent speech.
- Baha’u’llah
