Your mind belongs to society and your heart belongs to the universe. Be careful not to let your heart be ruled by your mind, because then you will forget how to be compassionate and to be humble. But also do not let your mind be ruled by your heart, because then you will forget how to remain calm. Find your middle. The pain that we may experience in our life will either make us soft or it will make us bitter. If it makes us bitter, we have given in to our ego. If it makes us soft, we find to our spirit. It is our own choice.
