“I am solid; I am free” means you’re not being pulled back by ghosts from the past and you’re not being dragged into the future; you are the master of yourself. To say these words is not autosuggestion or wishful thinking. When you’re able to dwell in the present, you truly do have solidity and freedom. You’re free from the past and the future, not rushing around like someone possessed. Solidity and freedom are the foundation of real happiness.
To have peace and joy and inner freedom, you need to learn how to let go of your sorrows and worries, the elements that create unhappiness.
