Praying five times a day defeminately was.
Over time, Zoroastrians developed the concept of worshipping in temples, sometimes called fire temples. The temples contain an inner sanctum (pavi) or platform where a fire is maintained or placed. This is because Zoroastrians face a source of light when they pray. In temples the source of light is a flame maintained in a fire urn. In certain temples, this fire is kept burning continuously, representing an eternal flame.
The orthodox will pray during each of the five divisions of the day (see our page on the Zoroastrian calendar) or gahs (see our page on the Avesta, scriptures) including reciting a special set of prayers before and after bathing.
Zoroastrians hold that the effectiveness of a person's beliefs is demonstrated in that person's deeds. While praying helps to reaffirm beliefs, a life based on good deeds is prayer in action. Our lives are the temples of our souls. This is a natural progression of the ethical creed of good thoughts, words and deeds, where good deeds are held to be most meritorious.
[Note: The word namaz or namaaz is used in modern Persian to mean prayer. It is derived from namazh, in turn derived from the Middle Persian namaach, a word with roots in the Avestan nemangh. Interestingly, in Avestan nemase-te means 'reverence to you'. Compare with Hindi namaste from Vedic Sanskrit namas-te meaning 'honouring-you'. The word namaz is now also used by Persian and Indo-Pakistani Muslims to mean prayer. Muslims have also taken the concept of praying five times a day and using a prayer cap or head-covering while praying from Zoroastrianism.]
