Practices and rituals

Throughout Zoroastrian history, shrines and temples have been the focus of worship and pilgrimage for adherents of the religion. Early Zoroastrians were recorded as worshiping in the 5th century BCE on mounds and hills where fires were lit below the open skies. In the wake of Achaemenid expansion, shrines were constructed throughout the empire and particularly influenced the role of Mithra, Aredvi Sura Anahita, Verethragna and Tishtrya, alongside other traditional Yazata who all have hymns within the Avesta and also local deities and culture-heroes. Today, enclosed and covered fire temples tend to be the focus of community worship where fires of varying grades are maintained by the clergy assigned to the temples.

The incorporation of cultural and local rituals is quite common and traditions have been passed down in historically Zoroastrian communities such as herbal healing practices, wedding ceremonies, and the like. Traditionally, Zoroastrian rituals have also included shamanic elements involving mystical methods such as spirit travel to the invisible realm and involving the consumption of fortified wine, Haoma, mang, and other ritual aids.

In Zoroastrianism, water (aban) and fire (atar) are agents of ritual purity, and the associated purification ceremonies are considered the basis of ritual life. In Zoroastrian cosmogony, water and fire are respectively the second and last primordial elements to have been created, and scripture considers fire to have its origin in the waters (re. which conception see Apam Napat).

A corpse is considered a host for decay, i.e., of druj. Consequently, scripture enjoins the safe disposal of the dead in a manner such that a corpse does not pollute the good creation. These injunctions are the doctrinal basis of the fast-fading traditional practice of ritual exposure, most commonly identified with the so-called Towers of Silence for which there is no standard technical term in either scripture or tradition. Ritual exposure is currently mainly practiced by Zoroastrian communities of the Indian subcontinent, in locations where it is not illegal and diclofenac poisoning has not led to the virtual extinction of scavenger birds.

The central ritual of Zoroastrianism is the Yasna, which is a recitation of the eponymous book of the Avesta and sacrificial ritual ceremony involving Haoma. Extensions to the Yasna ritual are possible through use of the Visperad and Vendidad, but such an extended ritual is rare in modern Zoroastrianism. The Yasna itself descended from Indo-Iranian sacrificial ceremonies and animal sacrifice of varying degrees are mentioned in the Avesta and are still practiced in Zoroastrianism albeit through reduced forms such as the sacrifice of fat before meals. High rituals such as the Yasna are considered to be the purview of the Mobads with a corpus of individual and communal rituals and prayers included in the Khordeh Avesta.

A Zoroastrian is welcomed into the faith through the Navjote /Sedreh Pushi ceremony, which is traditionally conducted during the later childhood or pre-teen years of the aspirant, though there is no defined age limit for the ritual. After the ceremony, Zoroastrians are encouraged to wear their sedreh (ritual shirt) and kushti (ritual girdle) daily as a spiritual reminder and for mystical protection, though reformist Zoroastrians tend to only wear them during festivals, ceremonies, and prayers.

Historically, Zoroastrians are encouraged to pray the five daily Gāhs and to maintain and celebrate the various holy festivals of the Zoroastrian calendar, which can differ from community to community. Zoroastrian prayers, called manthras, are conducted usually with hands outstretched in imitation of Zoroaster's prayer style described in the Gathas and are of a reflectionary and supplicant nature believed to be endowed with the ability to banish evil. Devout Zoroastrians are known to cover their heads during prayer, either with traditional topi, scarves, other headwear, or even just their hands. However, full coverage and veiling which is traditional in Islamic practice is not a part of Zoroastrianism and Zoroastrian women in Iran wear their head coverings displaying hair and their faces to defy mandates by the Islamic Republic of Iran.
