History off The Persian New Year by Iraj Bashiri

The oldest of Iranian traditions, Nowruz recalls the cosmological and mythological times of Iran. Its founder is a deputy of Ahura Mazda on earth, a position that imparts to him and the celebration a spiritual dimension and a particular sense of secular authority. The celebration is organized according to the dynamics of love between the Creator and his creation, the material world. The annual return of the spirits of the departed to their homes is celebrated by their offsprings according to primordial rites of which only a faint trace remains among the Persians and the Parsees of today. But that in no way diminishes the importance of the bond which is refreshed at every Nowruz.
In the mind of Iranians, the word nowruz invokes colorful images which are sumptuous, elegant, and opulent as well as delightfully simple, refreshing, and cordial. Although colored with vestiges of Iran's Mazdian and Zoroastrian past, the Nowruz celebration is neither religious or national in nature, nor is it an ethnic celebration. Jewish, Zoroastrian, Armenian and Turkish Iranians and Central Asians celebrate the Nowruz with the same enthusiasm and sense of belonging. Perhaps it is this very universal nature of the message of Nowruz that speaks to its wealth of rites and customs as well as to its being identified as the unique fount of continuity of the Iranian culture.
