Portrait of Bahá'u'lláh
From Bahai9
Seeing portrait may help one turn toward His likeness instead of mere imagination; not to be hung in Mashriqu'l-Adhkár[edit]
"As to thy question: “To whom should we turn?”—turn thou to the Ancient Beauty. God willing, a copy of His blessed portrait will in due course be despatched to thee so that when offering prayer thou mayest turn thyself in spirit towards that Holy Likeness, and not towards some mere figment of the imagination. Know thou, however, that at no time should His blessed portrait be hung in the Mashriqu’l-Adhkár."
