Love

Love is a choice of the heart, enlightened by the mind and carried out by the will.
Or,
Love is a choice of the mind, that becomes desired by the heart and carried out by the will.
Or,
Love is a choice of the will, that acquires a motivation from the mind until it becomes desired by the heart.

Love can begin from the heart, from the mind, or from the will, but it isn't love until the three are united.
