Find a place where you can feel completely at ease and say to yourself, Only I can destroy my peace, and I choose not to do so.

When performing this practice, locate a place where you will be able to sink deeply into the sensations of peace and calm. A park, a body of water, a garden, and the mountains are excellent choices. Being completely relaxed on a sofa can work well also. Do this practice daily for five minutes for one week, repeating the phrase until you own it. Over time it will become easier to quickly recognize when inner peace is abandoning you, and then you can do the practice again for a few days. When disruption arises around you, you'll have it handy: Only I can destroy my peace, and I choose not to do so.
