Lama Ole’s answer:
Look around and think, “Who might want to buy this fear?” Then think, “She won’t buy it, he won’t either, and she over there is also not interested!” So you notice, “Well, maybe this fear is useless!” and then simply throw it away.
Fear is also often connected to the breath. One breathes in a wrong and irregular way in a fearful situation. So one technique is to force oneself to breathe more slowly and deeply. Breathe in to a point just below the navel. Hold the breath for a moment in the belly as if in a vase—but not to the point of dizziness—then breathe out again. If you breathe deeply like this a couple of times, the fear will gradually go away.
The best way to deal with all fears and difficulties is to think, “All beings are my friends and will benefit if I’m doing well. So I will simply give my best in doing whatever is in front of my nose.” Then one does just that. This is also good if one gets scared before exams. Then think, “This is actually a complete conspiracy. The examiner wants me to pass; the teacher wants me to pass. It’s all in my favor.” And then go into the exam, sit down with your friends, explain to them everything they didn’t understand, and give it your best in the exam. Make your environment so friendly that you can only win.
