… the religion of God is one, and it is the educator of
humankind, but still, it needs must be made new. When thou dost plant a tree,
its height increaseth day by day. It putteth forth blossoms and leaves and
luscious fruits. But after a long time, it doth grow old, yielding no fruitage
any more. Then doth the Husbandman of Truth take up the seed from that same
tree, and plant it in a pure soil; and lo, there standeth the first tree, even
as it was before.
(‘Abdu’l-Baha, ‘Selections from the Writings of ‘Abdu’l-Baha’)
