The Sufis have a saying: "Praise Allah, and tie your camel to a post." This brings together both parts of practice: pray, yes, but also make sure that you do what is necessary in the world.
It takes courage to grieve, to honor the pain we carry. We can grieve in tears or in meditative silence, in prayer or in song. In touching the pain of recent and long-held griefs, we come face to face with our genuine human vulnerability, with helplessness and hopelessness. These are the storm clouds of the heart.
To learn to concentrate we must choose a prayer or meditation and follow this path with commitment and steadiness, a willingness to work with our practice day after day, no matter what arises.
