emotion greater than love:Bandagi

Love is a higher cognitive emotion,its basic emotional component is attraction.In what ever way you define it this basic character would be there.
Like love there is still a higher cognitive emotion for which I cannot find a word in English that truly reflects its  connotations and that is  "Bandagi"(servitude).Its is an extreme form of love in which you give yourself completely to the other being.
You can love many but there is only one person you give your heart to,whose beauty you praise above all,for whom you will change yourself,in whom you forget yourself and give your free will to.You become one and inseparable.
Some people have this emotion for God , some for an other human being,some have it for a particular philosophy or an activity for example  science or service of humanity.
But I think care should be taken before taking such a step because once you are in there is no question of using rationale, you have already given up yourself and that thing is going to change yourself.It will define what you will become : either a blessing or a curse for humanity.
