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 (Words of ‘Abdu’l-Baha to Mrs.
Mary L. Lucas, quoted in "A Brief Account of My Visit to Acca"
[Chicago: Bahá'í Publishing Society, 1905]; The Compilation of Compilations vol
II, Music)
