Another proof is this: Man's body may become weak or robust, sick or healthy, tired or rested; it may suffer the loss of a hand or leg; it may decline in material powers; it may become blind, deaf, dumb, or paralysed- in short, it may become gravely impaired. And yet, despite this, the spirit maintains its original condition and spiritual perceptions, suffering no impairment or disruption.
