Here is a technique for dealing with tense situations, especially if your emotions are starting to feel upset.
You can immediately begin to calm yourself by taking control of your breath. There is a link between our breath and our mind. By calming the breath, you also calm the mind.
There is a third part to this link — your subtle energy or aura. After you have calmed your own breath and mind, project your calm aura out to others involved in the situation. Especially extend energy from your heart out to include and embrace everyone around you.
Feel that you are all linked together in harmony. You can use variations of this technique in virtually every situation.
