When studying at present, in English, the available
Bahá’í writings on the subject of body, soul and spirit, one is
handicapped by a certain lack of clarity because not all were
translated by the same person, and also there are, as you
know, still many Bahá’í writings untranslated. But there is no
doubt that spirit and soul seem to have been interchanged in
meaning sometimes; soul and mind have, likewise, been interchanged
in meaning, no doubt due to difficulties arising from
different translations. What the Bahá’ís do believe though is
that we have three aspects of our humanness, so to speak, a
body, a mind and an immortal identity—soul or spirit. We
believe the mind forms a link between the soul and the body,
and the two interact on each other.
