Havan Gah

Zoroastrian daily devotion is built on the gahs, the five watches that partition the twenty-four hours, and Havan opens the cycle with the day's working light. The name is liturgical to the letter: havana is the mortar and pestle of the haoma rite, and the morning watch is when the priesthood performs the Yasna, the central act of worship in which haoma is pressed, so the whole first quarter of the day carries the name of an implement of sacrifice. For the ordinary believer the watch's duty is the gah prayer.

Zoroastrian practice frames each watch with the kusti ritual, the untying and retying of the sacred cord over the sedreh, the white undershirt, with its accompanying prayers; to this the worshipper joins the Avestan prayer proper to the watch, and the Havan Gah text greets the ratu, the lord, of the morning. That lord is Mithra, the great yazata of covenant and of the sun's ordering light, invoked with his epithet of the wide pastures, and with him the watch honours Savanghi and Visya, spirits of profit and of the settlement, the humble genii of the productive morning. The theology is characteristic: the day's divisions are not neutral time but personified order, each watch a being to be greeted, so that simply living through a Zoroastrian day means saluting the structure of the good creation five times, beginning here, with the sun up and the mortar ringing in the fire temple.

The five-gah cycle is one of the ancient world's clearest systems of fixed daily prayer, and its shape rewards comparison. Havan runs from sunrise to midday; Rapithwin holds the ideal noon; Uzerin carries the afternoon to sunset; Aiwisruthrem the evening to midnight; Ushahin the deep night to dawn. Each watch has its Avestan prayer, its presiding beings and its proper works, and together they mean that Zoroastrian time is never unowned: someone in the hierarchy of the good creation is always on watch, and the believer joins them by prayer.

Scholars of religion have long noted the family resemblance to the five daily prayers of Islam, which arose a millennium later in a neighbouring culture area, and to the canonical hours of Christianity; the traditions are distinct and the lines of influence debated, but the underlying instinct, that piety should be distributed across the day's natural divisions rather than concentrated in one act, is the same, and the Zoroastrian version is among the oldest continuously practised forms of it. The gahs also structure the liturgical rest of the religion: every high ceremony is assigned to its proper watch, the Yasna and Visperad to Havan, the great nocturnal Vendidad service to Ushahin, and the calendar's feasts are celebrated watch by watch. For the Zoroastrian diaspora today the gah prayers remain the portable core of practice, requiring no temple and no priest, only clean ground, the kusti, and the memorised Avestan that has ordered Iranian mornings for well over two and a half millennia.
