Joy, anger and sorrow, human feelings. There's always no way to do it when it's time to come. Isn't it? It's like Dogen Zen Master's "When you are alive, you should be alive, and when you die, you should die." There is always no way to suppress the emotions that should come. Emotions are part of who you are. As long as you don't get led by the nose.
Anger in ecstasy, destruction in anger, hopelessness in grief. All kinds of emotions come with actions in your realization. And once you are controlled by your emotions, you will often regret the decisions you make at that moment.
Emotions are a part of you, but they don't represent you. You can have any emotion, but emotions can't dictate what you do. You can sing when you are happy, you can cry when you are sad, or you can scold and vent when you are angry. And then what happens when your emotions dissipate? Do you feel embarrassed about what you did when you're happy? Do you feel worthless because of the pain? Or regret the decision you made when you're angry? All of this is happening in this world. Countless actions have changed course because of emotions. But emotions are also supposed to happen.
Emotions are not a problem, nor is forgetting yourself in your emotions. The only problem is to make the wrong decision and regret it, nothing more.
