As for the mind, it is the power of the human spirit. The
spirit is as the lamp, and the mind as the light that shines from it. The
spirit is as the tree, and the mind as the fruit. The mind is the perfection of
the spirit and a necessary attribute thereof, even as the rays of the sun are
an essential requirement of the sun itself.
- ‘Abdu’l-Baha (Table talks in Akka,
authenticated by ‘Abdu’l-Baha; ‘Some Answered Questions’ – 2014 revised
translation by the Baha’i World Centre)
