How you relate to people in your life, situations or your own body, will determine how you feel and think. If you relate in an angry fashion to your environment, your perception is of suffering. If you relate with love, compassion and acceptance, you can experience peace even in seemingly difficult situations.
For us to be fully whole in our Souls evolution and help others we need to go through different experiences. We learn by experiences. Allow yourself to look at some challenging experiences of your life and find the learning. Its your gift.
