Ethics in religion concept, it demands careful and sustained reflection by every man and woman before it can become part of one's life. Ethics that constitute a dharmic life - that is a moral, ethical, virtuous life - evolve in vedas and upanishads. Ethical subjects and questions are debated by various schools of Hinduism, quite extensively, in numerous texts on what is right conduct, when, how and why. Over time, new virtues were conceptualized and added by ancient Hindu scholars, some replaced, others merged. For example, Manusamhita initially listed ten virtues necessary for a human being to live a "dharmic" life: "Dhriti" (courage),
Vedas inspired later Hindu scholars such as Adi Shankara to classify each Veda into "karma-kanda" (कर्म खण्ड, action/ritual-related sections) and "jnana-kanda" (ज्ञान खण्ड, knowledge/spirituality-related sections). The texts considered "Vedic" in the sense of "corollaries of the Vedas" is less clearly defined, and may include numerous post-Vedic texts such as the later Upanishads and the Sutra literature. Texts not considered to be "shruti" are known as "smriti" (Sanskrit: ""; "the remembered"), or texts of remembered traditions. This indigenous system of categorization was adopted by Max Müller and, while it is subject to some debate, it is still widely used. As Axel Michaels
