Focus on things we want. Don't focus on things we don't want. If bad things happen to us, we recognize them, but we don't be affected by them. When we are so full of good energy, we won't be influenced by those people with negative energy. A white man told me his story with Dalai Lama. Once Dalai Lama had a seminar in his school. After spending a week with Dalai Lama, every one in the seminar changed his or her way of speaking. Every one became calm, gentle, and compassionate. The master shifted the energy of the people who attended the seminar to a positive energy. Unfortunately, the good energy didn't say with him for long. But he said the whole week was an amazing experience
