Embrace your emotions
Without feeling trapped in having to pursue them.
That is the goal and the path to the calm you seek.
Emotions are not the problem. It is how you deal with them that is.
If you lose yourself to the emotions you feel, then they become your master.
The next time you feel an emotion rising. Love or Hate. Anxiety or Comfort. Lust or Disgust. Do not respond to it immediately. Stop. Breathe. Separate yourself from whatever it is that is triggering it. Train yourself to contemplate what you are feeling even if for a moment. Acknowledge it, label it, contemplate it, and then ask yourself if responding is really what you want to do. Or do you simply want to let it go?
It is not the emotion that is the problem. That is simply your brain telling you something out there is about to effect you, in here.
It is up to you to decide how you want to respond.
After all, it is your life. Living in a meditative manner is the difference between pain and anguish, Love and joy.
