There is always desire to be something more within human. Usually it manifest itself through materialistic ways, sexual ways, through drugs or parenthood example. It is endless chasing, rat-race that leads nowhere but keeps you busy through own creation that people calls as life.
We can't remember our time as toddlers because we didn't exist in that time. We had no identity. Only when years has gone while we gathered data from our environment we created identity. When we have our identity, we decide what matters to us. Then we experience impulsive feelings when things didn't go as we wanted.
We are piece of life that creates own image and plays it (Genesis 1:27 So God created man in His own image). We get so tangled to our own creation that it can kill us and bring us into hell. We think that something or someone causes our misery even when we alone create everything within.
We have all this mysterious desire to do something, be something more. It usually manifest itself through sexual ways, materialistic ways, through parenthood, dating, drugs, games, food, alcohol.. you name it. Through that it leads nowhere, it keeps us happy for a moment and then we need more. So where we are now? We are piece of life that want to experience bigger part of it. Through physical ways it finds not that part and when that need to expand finds no expression we create this pain within. So what to do? This is what meditation is all about. We don't want to identify to our thoughts or to our outward senses. That is just the data we gathered from the physical and created self from it. When we learn to be still, just be as piece of life, something start to happen that seems to expand you into everywhere. It seems to that consciousness, awareness is the basic that exist and everything else is manifest of it.
What (((they))) wan't is to bind us more and more into physical, sins, into that rat-race i wrote about above, so that we wouldn't learn or even think about this.
