According to the Bahá’í teaching the human body serves a
temporary purpose in the development of the soul, and, when
that purpose has been served, is laid aside; just as the eggshell
serves a temporary purpose in the development of the chick,
and, when that purpose has been served, is broken and discarded.
‘Abdu’l-Bahá says that the physical body is incapable
of immortality, for it is a composite thing, built up of atoms
and molecules, and, like all things that are composed, must, in
time, become decomposed.
