When the soul attaineth the Presence of God, it will assume
the form that best befitteth its immortality and is worthy of its celestial
habitation. Such an existence is a contingent and not an absolute existence,
inasmuch as the former is preceded by a cause, whilst the latter is independent
thereof. Absolute existence is strictly confined to God, exalted be His glory.
(Baha'u'llah, Gleanings from the Writings of Baha'u'llah)
