Sri Aurobindo
Letters of Sri Aurobindo
Volume IV - Part 3
The physical pain is obviously due to attacks – any physical 
cause being only a means for the action of the attack. I have often seen that when the mind and consciousness have rejected the attacks, the contrary forces fall on some weak point in the body hoping that by pain or illness they will depress the consciousness and so make it less strong to resist and reject them. We must see whether this recurrence of the pain cannot be quietly pushed out altogether.
