Briefly...
Briefly, affection of human to development and perfection, to wisdom and beauty, to goodness and justice is a genuine affection, forever and immortal; and waiting for the advent of a great universal peacemaker is the ultimate of this affection. (Attention!) How it is possible that love of multilateral perfection is available inside the human soul but doesn’t wait for such matter! If is it possible to achieve the perfection of human society without that!
Therefore, those who had no failure and crisis in their lives have such feeling inside their souls … in one side. On the other side, as limbs and parts of human body helps his perfection and development and we cannot find a limb in body which has no role in this developing movement, mental characteristics of human are also like this; which means any of them has an effective role in development of his genuine goals.
For example, “fear of dangerous factors” which is available in any human is for saving him from the danger. “Anger”, when the person finds his benefits in danger, is a mean of increasing the defensive power and mobilization of all reserved physical and spiritual powers for saving his benefits from the danger.
Therefore, love of perfection, love of peace and justice are also the means of reaching this great goal and is like a powerful engine, which moves the wheels of human soul forever in this way, and helps him for achieving a world full of peace and justice.
On the other side, feelings and mechanisms, which are available in the body and the soul, cannot be in disharmony with the universe of existence; because the entire universe of existence is an integrated unit and our existence cannot be separated from the rest of the universe.
We can conclude well from this integration that any genuine love and affection, which is available in our soul, is the reason for having its “loved one” and “goal” out there in the universe and this love is a mean for moving us toward that. It means that if we become thirsty and have the affection of water then it is the reason for the existence of water that the universe of creation has placed its affection inside us.
If we have the affection of opposite sex then it is reason for the existence of opposite sex out of us; and if we have the affection of beauty and wisdom then it is the reason for the existence of beauties and wisdoms in the universe of existence.
