Atman or the Self cannot be affected by germs, microbes, bacilli, cholera, pyorrhoea, plague, etc. Weaknesses, depression, uneasiness, feeling out of sorts, morbidity have no place there. Germs and diseases take to their heels if anyone simply remembers the Atman or one's own Self. During illness, detach yourself from the body. Connect the mind with the Buddhi and soul. Again and again assert: "I am the bodiless, diseaseless, all-pervading, immortal Soul or Atman." The disease will take to its heels.
Incessant remember of God destroys the misery of the whole world and fills a person with highest Bliss.
