The Soul and Infirmities of the Body
Know thou that the soul
of man is exalted above, and is independent of all infirmities of body
or mind. That a sick person showeth signs of weakness is due to the hindrances
that interpose themselves between his soul and his body, for the soul itself
remaineth unaffected by any bodily ailments. Consider the light of the
lamp. Though an external object may interfere with its radiance, the light
itself continueth to shine with undiminished power. In like manner, every
malady afflicting the body of man is an impediment that preventeth the
soul from manifesting its inherent might and power. When it leaveth the
body, however, it will evince such ascendancy, and reveal such influence
as no force on earth can equal. Every pure, every refined and sanctified
soul will be endowed with tremendous power, and shall rejoice with exceeding
gladness.
Consider the lamp which is hidden under a bushel.
Though its light be shining, yet its radiance is concealed from men. Likewise,
consider the sun which hath been obscured by the clouds. Observe how its
splendor appeareth to have diminished, when in reality the source of that
light hath remained unchanged. The soul of man should be likened unto this
sun, and all things on earth should be regarded as his body. So long as
no external impediment interveneth between them, the body will, in its
entirety, continue to reflect the light of the soul, and to be sustained
by its power. As soon as, however, a veil interposeth itself between them,
the brightness of that light seemeth to lessen.
Consider again the sun when it is completely hidden
behind the clouds. Though the earth is still illumined with its light,
yet the measure of light which it receiveth is considerably reduced. Not
until the clouds have dispersed, can the sun shine again in the plenitude
of its glory. Neither the presence of the cloud nor its absence can, in
any way, affect the inherent splendor of the sun. The soul of man is the
sun by which his body is illumined, and from which it draweth its sustenance,
and should be so regarded.
(Baha'u'llah, Gleanings from the Writings of
Baha'u'llah, p. 154-6)
Evolution of the Soul
Regarding your questions
concerning the condition of the soul during illness. The passages in the
"Gleanings"
make it quite clear that physical ailments, no matter how severe, cannot
bring any change in the inherent condition of the soul. As Bahá'u'lláh
says: 'The spirit is permanent and steadfast in its station'. The
veil or hindrance that interposes between soul and body during physical
disease is sickness itself. Sickness reveals itself. Sickness reveals a
lack of balance in human organism, an absence of equilibrium in the forces
essential for the normal functioning of the human body.
