The Jashan, or Afringan, is the general-purpose ceremony and the one most ordinary Zoroastrians will actually see. It requires two priests, or sometimes one, and a tray laid with fruit, flowers, milk, wine, water and a small fire vase with sandalwood and frankincense. During the recitation the priests exchange flowers across the tray in a prescribed pattern, hand to hand — the exchange representing the linking of the spiritual and material worlds — and afterwards the food is shared with everyone present. It is held for thanksgiving, for memorials at set intervals after a death, for the seasonal festivals, for the consecration of a new house or office, and at the founding of institutions. Because it can be performed in a living room, a hall or a company boardroom, and takes under an hour, it has become the ceremony through which most lay Zoroastrians encounter priests, particularly in the diaspora where fire temples are scarce.
