Abstract
In this article I will discuss the meaning of the word "ethics" before moving on to the relation between religion and ethics in India, namely some problems with the word rinri, the Japanese translation of "ethics." Then I will discuss the teachings of Nanak, who established his own school of thought in India in the Middle Ages, and clarify how his religious teachings were linked with the everyday ethics of the Sikhs, how the Sikhs applied the teachings in their daily life, and how they manifested their uniqueness in the real world. The rational and practical teachings of the Sikhs are manifested strongly in model actions for daily life, and the Sikhs have contributed greatly to the modernization of India. The attempt by the Sikhs to practice their religious ideals within the current world is a different model than that of Europe, but is an example of the unity of religion and ethics.
