The aim is this: The intention of the teacher must be pure,
his heart independent, his spirit attracted, his thought at peace, his
resolution firm, his magnanimity exalted and in the love of God a shining
torch. Should he become as such, his sanctified breath will even affect the
rock; otherwise there will be no result whatsoever. (‘Abdu’l-Bahá, ‘Tablets of
the Divine Plan’)
