In many religions, there is some kind of ritual that signifies losing the self and starting a new life. (Christians perform a baptism, Buddhists reach enlightenment, Hindus there is a bathing ritual, Muslims say a prayer.) That feeling of renewal doesn’t have to be a one-time event in one’s life.
It could be going to sleep and waking up. It could be having surgery and coming out the other side. It could be starting a new job. It could also be walking through a door or starting your car.
Renewal is an act of awareness. Starting today, right now, at this moment, I am going to be the person I say I want to be.
