There are emotions and then there are the effects of emotions. But
all emotions can cause incoherence.
You know you are incoherent when your decisions are wrong, and take you down the path of self-destruction or hurting yourself or someone else. When you can’t hear what someone is saying. When you find your attention wandering. When you are not present.
Some emotions’ energy goes outward, other emotions’ energy goes inward.
Either type of emotions,
in a weak person, wreak havoc and cause devastation. A strong person can harness their outward emotions to move mountains, to accomplish, to achieve, to grow.
And a strong person can accept their inward going emotions as not necessary, not rolevant, and let them go.
