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-Baha (Words of ‘Abdu’l-Baha, recorded by Mary Lucas
during her pilgrimage in 1905; ‘A Brief Account of My Visit to Acca’, by Mary
Lucas)
