Every one of the friends should highly praise the other and each should regard himself as evanescent and as naught in the presence of others. All matters should be consulted upon in the meeting and whatever is the majority vote should be carried out. I swear by the one true God, it is better that all should agree on a wrong decision, than for one right vote to be singled out, inasmuch as single votes can be sources of dissension, which lead to ruin. Whereas, if in one case they take a wrong decision, in a hundred other cases they will adopt right decisions, and concord and unity are preserved. This will offset any deficiency, and will eventually lead to the righting of the wrong. (‘Abdu'l-Bahá, The Compilation of Compilations, vol. I, Consultation)
