This is a condition that often affects spiritually advanced or highly intellectual people.
It is simply a manifestation of an inward condition.
When one is making an effort to be clean in thought and deed (to clean the inside) our sensitivity to our surroundings is heightened.
These germs have always been there, we are just hypersensitive to them now because we are so aware of our own inner condition.
Those walking around in a trance unaware of what is happening inside of them, go blissfully through life without knowledge of the causes of most things that happen in their lives.
Those that know themselves know what it is that lurks in hidden places as well as right in front of their eyes.
This is easily fixed when one realizes the cause.
When one is concerned about keeping the inside of one's self clean we develop an unhealthy obsession with our outer environment knowing how dirty it can be.
Our heightened sensitivity to germs should cause us to be more cautious but not obsessed.
Germs are here to stay because they are necessary, it is up to us to stay healthy and stay out of unhealthy environments if possible.
