The answer Remains elusive in part because love is not one thing. Love for parents,partners,childrens,country,neighbour, GOD and so on all have different qualities .Each has its variants blind,one sided,tragic,steadfast,fickle,reciprocated,misguided,unconditional.At its best,however,all love is a kind a passionate commitment that we nurture and develop,even though it usually arrives in our lives unbidden.Thats why it is more than just a powerful feeling.Without the commitment ,it is mere infatuation .Without the passion,it is mere dedication.Without nurturing,even the best can wither and die.
