In the world of existence physical things have a connection
with spiritual realities. One of these things is the voice, which connects
itself with the spirit; and the spirit can be uplifted by this means -- for
though it is a physical thing, it is one of the material, natural organizations
-- therefore, it is effective.
('Abdu'l-Bahá's words to Mrs. Mary L. Lucas, as
quoted in "A Brief Account of My Visit to Acca" (Chicago: Bahá'í
Publishing Society, 1905); The Compilation of Compilations vol II) (To read the entire talk please visit Talks of
