We live between our conscious mind (Which can be thought as ego-mind) and our unconscious mind (Which can be though of as body-mind). Our ego has to be able to handle its role as a "double agent," balancing the needs of life in the conscious, visible, world of concrete reality, and the needs of the life of our psyche, our unconscious, body-mind. We live with a foot in each world. We walk two paths at the same time. The way to do that is to always be aware of the other world while we are consciously engaged in this world. This makes the need for the right kind of emptiness, stillness and silence crucial/essential/mandatory to our role in coordinating life in two worlds at once. We are always receiving input from our body-mind and needing to apply it to our life in the conscious world. We have to be aware of what our unconscious is saying, interpret it correctly, and altering our conscious life to take our unconscious concerns/needs into account. Our task is to live in accord with the unconscious by adjusting our life in the conscious world. It requires time and attention for us to do this. Our nighttime dreams connect us with the unconscious. Slips of the tongue, emotional reactions (Falling in love, attraction/repulsion, anger/hatred, tears/fear/anxiety...), physical symptoms, something catching our eye, sudden interests, etc., are places we need to explore, investigate, consciously for inner messages providing guidance in our external life. We have to do the work of making the unconscious conscious, and regulating our life as required in order to do that. Our life is not ours to do with as we will. Our life is to be aligned with the inward drift of our psyche/soul, in a "Thy will not mine be done" kind of way. The quality of our life improves in direct proportion to the degree we are able to do this, and deteriorates in proportion to the degree in which we refuse/fail to do it. Attend the inner, adjust the outer. Our mantra for life.
