…although the degrees of being are various, yet all are
good. Observe the human body, its limbs, its members, the eye, the ear, the
organs of smell, of taste, the hands, the fingernails. Notwithstanding the
differences among all these parts, each one within the limitations of its own
being participateth in a coherent whole. If one of them faileth it must be
healed, and should no remedy avail, that part must be removed.
- ‘Abdu’l-Baha (‘Selections from the Writings of ‘Abdu’l-Baha’)
