Realise, through practices, what destroys ego, your sense of self, to attain a perception of what buddhists call no-self. That's why life's greatest difficulties often come as a blessing. I think it's what Jesus meant by being poor in spirit. So much unnecessary struggle just comes from being full of ourselves. Ego is big and burdensome. Make it small and light, so doesn't weigh you down, so that you can just get on with doing amazing things in your time here.
