Conventional morality is based on the instinct of self-preservation, and it often turns out to be selfish in actual human activity and in society. This egoistic tendency is the cause of various sufferings, conflicts, antagonism, fights, and in wars among nations in extreme cases. Hence, eradicating egoism or selfish tendency in our mind is the first step toward supreme morality. Morality expounds on how to eliminate the selfish and egoistic disposition in our mind.
The world's sages followed the law of the Universe or the will of God. Their actual mentality and conduct are characterized by a deep love of benevolence towards all living things, including all human beings and all matters supporting us. More precisely, their impartial and unconditional love or benevolence towards all beings greatly moved and led people of their times to believe in the existence of God, and His essential nature to be just and benevolent. Thus, to have faith in God is to actualize this benevolence in social life, regardless of people's dogmas or religious affiliations.
The concept of the precedence of duty over personal rights derives from the world's sages to the effect that what one gains is the result of one's efforts.

All the sages of the world manifested this principle by working wholeheartedly for the promotion of true happiness of all human beings. According to this principle, we need to fulfill duties in order to actualize our rights.

It is our duty to express our gratitude to, and live up to the spirit of, the ortholinons.
