Bahá'í consultation refers to the method of discussion and decision making which is described in the Bahá'í writings, and which is used in all levels of Bahá'í administration.
'Abdu'l-Baha states:
The prime requisites for them that take counsel together are purity of motive, radiance of spirit, detachment from all else save God, attraction to His Divine Fragrances, humility and lowliness amongst His loved ones, patience and long-suffering in difficulties and servitude... The members thereof must take counsel together in such wise that no occasion for ill-feeling or discord may arise. This can be attained when every member expresseth with absolute freedom his own opinion and setteth forth his argument. Should any one oppose, he must on no account feel hurt for not until matters are fully discussed can the right way be revealed. The shining spark of truth cometh forth only after the clash of differing opinions. If after discussion, a decision be carried unanimously, well and good; but if the Lord forbid, differences of opinion should arise, a majority of voices must prevail.
