I do know however, that without love in your life it becomes pretty meaningless. Humans were not made to be emotionless beings. Humans have great capacity for great emotion and love being the strongest one of them all. Wars have been fought over it, people have conquered insurmountable obstacles for it, lives were lost in the name of it and souls have been saved because of it.
Love in all of its forms is a true gift, to be able to give it freely without asking anything in return. Loving someone or something just for what they are is a selfless act. Of all the virtues the the human being has been in body with, love is the greatest treasure of all.
Love thy kinsman as one would love thyself.
