I found this article from DailyOm.com and it was too good not to share.
Approaching life with an open heart means that we have opened the door to a greater consciousness.
Spiritual teachers have always pointed to the heart as the seat of consciousness, and recently Western science has found evidence to support this realization. It turns out that the heart has its own central nervous system and is not simply under the rule of the brain as formerly believed. Anyone who has taken the time to explore the heart knows this and, more important, has realized that the heart is the source of our connection to a consciousness greater than the ego. Approaching life with an open heart means that we have opened the door to this greater consciousness, taking up residence alongside it in the seat of our soul. Fortunately, at this time there is a lot of support for this shift energetically as well as practically. To some degree, approaching life with an open heart is as simple as shifting your attention onto your heart.
Eventually you will be able do this any time, any place, but at first it may help to try it in a quiet place where you won’t be disturbed. Simply sit with your eyes closed and draw your breath into your heart. As your breath expands your chest cavity, your heart expands and opens. You may feel tenderness or sadness in your heart, and you may also feel relief. Any emotions that arise can be effectively witnessed and healed through the meditation process, which benefits both your physical heart and your energetic heart. The more you practice, the more you will find your heart opening to your own presence and to all the situations your life brings.
When we open our hearts, they may feel tender and vulnerable, which simply means that they need our loving attention as we cleanse and heal them of past hurts and blockages. This process asks us to practice some of the heart’s greatest lessons, patience, compassion, and unconditional love. On the other hand, we may take up residence as effortlessly as a bird returns to its nest. Either way, approaching life with an open heart simply means returning to our true home.
