When Newars refer to themselves as Buddha Margi (Buddhist) or Shiva Margi (Hindu), they often do so only to indicate that they employ a Vajracharya or Bahun priests; even this does not hold true, though, as many jyapu (farmers) call themselves "Hindu" and attend Hindu festivals, yet still use Vajracharyas. In any case, Newar rituals vary little from Hindu to Buddhist.
Puja (an act of worship) is performed to gain the favor of deities for material requests as often as for "spiritual" reasons. It is a profound and very personal ritual. An integral part of all Newar rituals is the "puja of five offerings", consisting of flowers (usually marigolds), incense, light (in the form of butter lamps), sindur (colored powder) and various kinds of purified food (usually rice, dairy products, sometimes sweets). Before darshan (audience with a deity), the devotee or the priest uses consecrated water to wash him or herself and to bathe the deity. After the deity has symbolically accepted and eaten some food, the remainder is taken back by the devotee as prasad (consecrated food). This, along with a tika made with the colored powder, confers the deity's blessing and protection.
Priests are ordinarily engaged for the more important life-cycle rites (birth, marriage, death) or for larger seasonal festivals; wealthier Newars may also seek private consultations at times of illness or important decisions. Bahun priests don't perform animal sacrifices, but they do preside over the rituals that precede them. This brings up one of the rare differences between Hindu and Buddhist Newars : while Hindu Newars are enthusiastic sacrificers – they call the bloody ninth day of Dasain festival Syako Tyako (roughly, "the more you kill, the more you gain") – Buddhists seldom participate. During dasain, Tibetan monasteries in Nepal hold special services to pray for good rebirths of the sacrificed animals.
