Vibration, Compatibility & Transmission
Compatibility is an extremely superfine concept. It is always about the relationship between two or more subjects. It is about the similarity or difference in vibrational patterns between two subjects. For example, when two musical instruments are in tune with each other, the music is harmonious. When they are out of tune, it is awful to listen to the music performed.
When two subjects are in harmony, when they resonate at the same frequency, there is harmony and similarity. This sort of togetherness is compatibility. It occurs in all aspects of our lives from the most basic physical aspects, like the foods we eat, to more subtle feelings of comfort or discomfort. For example, when you are taking one medication, if by accident you take something that is not compatible with that drug, there is a clash. There is a war inside and you suffer as a result.
