Indo-European parallels for "Dharma" are known, but the only Iranian equivalent is Old Persian "darmān" "remedy", the meaning of which is rather removed from Indo-Aryan "dhárman", suggesting that the word "Dharma" did not have a major role in the Indo-Iranian period, and was principally developed more recently under the Vedic tradition. However, it is thought that the "Daena" of Zoroastrianism, also meaning the "eternal Law" or "religion", is related to Sanskrit "Dharma". Ideas in parts overlapping to "Dharma" are found in other ancient cultures: such as Chinese Tao, Egyptian Maat, Sumerian Me.
