Abstract
Merriam-Webster dictionary defines an apostle as a person who initiates a great moral reform or who first advocates an important belief and system [1]. Similarly, the Cambridge Dictionary states that an apostle is someone who strongly supports a particular belief or political movement [2]. The Free Dictionary by Farlex describes an apostle as a person who pioneers an important reform movement, cause, or belief; a passionate adherent; or a strong supporter. In the light of the above meanings of the term ‘apostle’, one can easily say that Guru Nanak was an apostle as he initiated great moral and social reforms in the Indian society of his times, as is evident from his life and works. He promoted an important belief system (moral code) of truthful living [4]. He states: Sacẖahu orai sabẖ ko upar sacẖ ācẖār. Truth is the highest virtue, but higher still is truthful living. (M. 1, SGGS, p. 62) The second part of the current topic is related to the term “Peace.” Peace has always been among humanity's highest values. The most popular (Western) view of peace is an absence of dissension, violence, or war. But peace is also seen as concord, or harmony and tranquility. It is viewed as peace of mind or serenity, especially in the East [5]. Peace of mind (also called inner peace) indicates a state of being mentally and spiritually at peace. It refers to having enough knowledge and understanding to keep oneself firm during discord or stress. We need some degree of inner peace in our own lives to be effective in helping to build peace in our organizations, communities, societies, and the world.
