The key is awareness. Awareness of what? Aware that you are alive, breathing, eating, drinking, walking, sleeping. But we are constantly have something in our mind. We need an object to concentrate. Most of the time we lost in our thoughts. Thoughts comes randomly to our mind. Otherwise you need something nagging in your mind to hold on. Then our thought move around it. Why this happen to me? Constantly we ask this question. So what is being aware. It is simply observe what is around you and in you. Many believe that this is the key to spirituality. Prayer is basically an attempt to aware about a deity or god.
Aware that you are breathing, Alive.
