O beloved of God, endeavor with your hearts and souls, that
ye may be qualified with the morals and attributes of the Blessed Perfection,
and partake of the bounties of His sanctity; that ye may become signs of unity
and standards of oneness, discover the essence of singleness and sing harmonies
and lays in this divine garden, in merciful melodies; that ye may become as
thankful birds, and sing a song in the rose-garden of existence which may
astonish minds and senses; that ye may hoist a standard on the apex of the
universe which may flutter in the winds of favor, and plant a tree in the field
of the visible world which may bring forth fruits of the utmost delicacy and
freshness. (‘Abdu’l-Baha, ‘Tablets of
Abdu'l-Bahá', vol. 2’)
