Attired in the garb of a traveler, coarsely clad, taking
with Him nothing but his kashkúl (alms-bowl) and a change of clothes, and
assuming the name of Darvísh Muḥammad,
Bahá’u’lláh retired to the wilderness, and lived for a time on a mountain named
Sar-Galú, so far removed from human habitations that only twice a year, at seed
sowing and harvest time, it was visited by the peasants of that region. Alone
and undisturbed, He passed a considerable part of His retirement on the top of
that mountain in a rude structure, made of stone, which served those peasants
as a shelter against the extremities of the weather.
