Know thou that the distinction between male and female is an exigency of the physical world and hath no connection with the spirit; for the spirit and the world of the spirit are sanctified above such exigencies, and wholly beyond the reach of such changes as befall the physical body in the contingent world. 

- ‘Abdu’l-Baha  (From a Tablet; included in a Memorandum from the Research Department of the Universal House of Justice, 23 February 1992)
