November 18, 1918
I appreciated your little note. I observe that you have survived the operation. I hope that it will be entirely successful, so that India may for many a year to come continue to hear your songs. For me I do not know when I shall be able to leave this sickbed of mine. Somehow or other, I cannot put on flesh and gain more strength than I have. I am making a mighty attack. The doctors of course despair in face of the self-imposed restrictions under which I am labouring. I assure you that they have been my greatest consolation during this protracted illness. I have no desire whatsoever to live upon condition of breaking those disciplinary and invigorating restrictions. For me, although they restrict the body somewhat, they free the soul and they give me a consciousness of it which I should not otherwise possess. "You can't serve God and Mammon" has a clearer and deeper meaning for me after those vows. I do not infer that they are necessary for all, but they are for me. If I broke them I feel that I should be perfectly worthless.
Do let me have an occasional line from you.
