I think modern society is so plugged up, it can't see straight! We are so constipated, we forgot how to let go of our emotions. Back in the past, and in many communal lifestyles today, it is natural to express - to release emotions; not to feel embarrassed or guilty about them. In these communities, nobody justifies why they cry or why they get sad or down one day. They just feel it and move on. That's it. Western societies make such a huge parade around emotions like "I did it; but I won't do it again. I promise." Or "something is wrong with me."
Justifying and explaining why you feel a certain way is putting way to much meaning on something as natural as a bowel movement. The modern society believes so strongly that we shouldn't express; instead we would rather pop pills and go for some specialized treatment to fix ourselves. Emotions are like the gut. If they are stuck, the messy matter will rot and cause further damage to the system.
The obstruction of emotions in our body, just like the obstruction of stool matter in our intestines, is virtually the same thing. Obstruction or constipation causes health, mental, and emotional problems. Let GO of your emotions with pride. They are as natural as your skin, teeth, hair, freckles, liver, and heart. Learn to appreciate them. Perhaps releasing our emotions regularly and with love would bring out the best in all of us.
