Each one’s pain is different. You can empathize with them but you cannot always understand what someone is going through. Even if they are a long-time companion, a sibling, a parent or a child. No amount of empathy can help the other person either. They have to go through what they have to go through. Ultimately, everyone has to deal with their pain themselves; they have to understand it, negotiate with it and accept it. Acceptance does not take away the pain, but it instantaneously frees you of all suffering. So, if you you love someone who is dealing with intense pain, encourage them to embrace it; help them to be non-suffering. Being non-suffering holds the key to Happiness.
