If they arise to teach My Cause, they must let the breath of
Him Who is the Unconstrained, stir them and must spread it abroad on the earth with
high resolve, with minds that are wholly centered in Him, and with hearts that
are completely detached from and independent of all things, and with souls that
are sanctified from the world and its vanities. It behoveth them to choose as
the best provision for their journey reliance upon God, and to clothe
themselves with the love of their Lord, the Most Exalted, the All-Glorious. If
they do so, their words shall influence their hearers. (Bahá'u'lláh, ‘Gleanings
from the Writings of Bahá'u'láh’)
