I hope that each and all of you may become like unto verdant
and green trees so that through the breezes of the divine spring, the
outpouring of heaven, the heat of the Sun of Truth, you may become eternally
refreshed; that you may bear blossoms and become fruitful; that you may not be
as fruitless trees. Fruitless trees do not bring forth fruits or flowers. I
hope that all of you may become friends of the paradise of Abhá, appearing with
the utmost freshness and spiritual beauty. I pray in your behalf and beg of God
confirmation and assistance. (‘Abdu’l-Baha, from a
talk, April 13, 1912, New York; ‘The Promulgation of the Universal Peace’)
