Bonds of love are essential to all sentient life - to creating and fostering kindness and compassion and caring in the world. These bonds - love - give us strength, faith, tenacity and the will to do good.
Love and attachment are not synonymous. Non-attachment is simply about being able to let go, because everything in this life is fleeting. Nothing stays. This doesn't mean you shouldn't be grateful and happy for what you are given, now, just that when the time comes, you strive, find a way to let it go without regret.
Attachment is not love at all. When you love something, sometimes you have to find a way to let it go. Although it is a tenet of being a Jedi, it is something everyone should embrace. It is not exclusive to the life of the duty-bound.
For a Jedi, it means putting the the good of many, above the good of one, always. A Jedi's topmost priority is always the will of the Force, but does that mean it is demanded that they cannot have anything else at all? That there can be no second on the list, or third? That there can be no list?
Peace does not mean lack of emotion, because emotion *is*. In contrast, it is accepting emotion. There is no emotion in the Force; the Force is a philosophical ideal, something to strive for in duty and service. But a Jedi has life, as well as duty. Duty is first, but life is there unavoidably and life needs nourishment - water, food, comfort, companionship - to be sustained in any measure.
Duty is utmost in a Jedi's life. And for this, other equally as important responsibilities, family, cannot be taken on. But not because there is none that could handle it, only because it is unknown who could handle it, and it would remain unproven until proven too late.
