...rest ye not, seek ye no composure, attach not
yourselves to the luxuries of this ephemeral world, free yourselves from every
attachment, and strive with heart and soul to become fully established in the
Kingdom of God. Gain ye the heavenly treasures. Day by day become ye more
illumined. Draw ye nearer and nearer unto the threshold of oneness. Become ye
the manifestors of spiritual favours and the dawning-places of infinite
lights!... (‘Abdu’l-Baha, ‘Tablets of the Divine Plan Revealed by 'Abdu'l-Bahá
to the North American Bahá'ís’; The Compilation of Compilations, vol. II,
Guidelines for Teaching)
