What is the measure of the heart

What is the measure of the heart?? We use our heart in matters of love and what becomes of it in the long run?? At first the passion is a fire burning hotter than a star, holding your love by a open fire in the outdoors. Gently caressing souls in front of a fire and that time feels so wonderful.... Till the time comes when the heart is still filled with love, but our mind is filled with other thoughts of money, power, other bodies. Look inward at your heart and what does it tell you, yes i love this one and I want no one but that person, but again the mind tell you about the encounter and hope of another that creates the delemia of heart and mind! What to do?? Does it feel like the the song "House of the Rising Sun," by the Animals and it feels like and you can feel and see it in the movie Casino in the end when everyone is dying and it goes to the part where Ginger is dying from being on to much drugs.. The song is playing and she gently slides down to die in a cheap motel... A little bit dramitic but matters of the heart are serious and the weight of the matters can hinder your life. What now...
