Because the human self is so deeply entrenched in separation and sees "the other" and the outer world as inherently separate and therefore potentially dangerous, peace slips beneath your notice as you engage your day-to-day world.
The depths to which you exist are beyond (yet include) your conscious mind. But when you start your day you locate your sense of self firmly in the mind, which is like living in the attic of a beautiful and wonderful house. You see the mind as being the principle doer and responder to all life's challenges and refer to it accordingly. The key is to sink into the depths of Awareness every day and do whatever it takes to do this. If it causes you to push away other obligations, then do so.
This is the real Self you are sinking into, rather than the tip of the iceberg you value so much. And, like icebergs, there is so much more beneath the surface. You can live from this great depth without losing anything. In fact, the enormity of this Self is so vast, many of your concerns will shrink in importance and you will feel lighter than ever before.
But are you willing? So many fear letting go of their mental focus as though the mind is holding their world together. In fact it is, but not the way you think. The projections of the mind provide the floor show, if you will, but what you are reaching for generates the stage itself. And yes, you can live from Awareness always and in all ways. But just as your day-to-day world is filled with things for you to do and learn, you must make time to give your human organism an opportunity to experience the freedom of Awareness and absorb the sensation of Freedom, instead of the weight of bondage.
Your central nervous system and your charkas are wired in such a way that your focus is geared to see only a certain spectrum of light and matter. Do not fault yourself for being absorbed by this experience. Realize that what you are struggling with is inherent on the "set" you find yourself. But you can and will become fully aware, fully awake, and to fuel this process, you must desire it with all your heart. Those who your world calls truly enlightened all tell stories of wanting only God, only This. They made this desire the sole focus of their lives. And you can too. If you can subordinate the trappings of your life as it is and give yourself wholly over to the Divine, then you will move into that which you seek. Putting worldly concerns first, because you fear losing what you have, will only delay you. It is not bad or wrong to want material things or to maintain a worldly life, but we encourage you to examine which really comes first--moment to moment, day to day.
