The acceptance of a person into the Bahá'í community should be based not on whether he is leading an exemplary life, but in whether the Assembly is reasonably certain that he is sincere in this declaration of faith in Bahá'u'lláh and that he knows of the laws which would affect his personal conduct, so that he does not enter the community under a misapprehension. The question of mental instability has no bearing upon the acceptance of an enrollment unless it is of such a nature that it affects the ability of the declarant to judge whether or not he believes in Bahá'u'lláh.
