'Abdu'l-Bahá is constantly engaged in ideal communication
with any Spiritual Assembly which is instituted through the divine bounty, and
the members of which, in the utmost devotion, turn to the divine Kingdom and are
firm in the Covenant. To them he is whole-heartedly attached and with them he
is linked by everlasting ties....

Compilation of Compilations, vol. II, The Local Spiritual Assembly)
