Emotions: Happiness and Security

We know that the Five Transformations explain how energy moves in cycles through various stages of transformation in a predictable pattern, such as the seasons, times of the day etc. and that we classify the organs of the body according to these stages. But did you know that our emotions are also classified in this way? 

For example, if we have an illness related to our lungs or large intestines, we tend to experience feelings of sadness or depression. But when these organs are in good health, we experience happiness and a strong sense of security!
