Tara Temple Morning Prayer, Bodh Gaya

The morning prayer at Tara Temple, October 17, 2019.

The courtyard is prepared by the monks.

Participants sit down and wait for the ceremonies to begin.

The monks take their place at the front.

The ceremony begins with the Anjali mudra.
Anjali mudra is performed by pressing the palms of the hands together. The fingers are together with fingertips pointing up. The hands are pressed together firmly and evenly.

The gesture is used for both greetings and farewells but carries a deeper significance than a simple "hello" or "goodbye".
The joining together of the palms is said to provide a connection between the right and left hemispheres of the brain and represents unification. This yoking is symbolic of the practitioner's connection with the divine in all things.

Holding each the vajra and bell in separate hands.
The vajra and bell are used in many rites by a lama or any Vajrayana practitioner of sadhana.

The vajra is representative of upaya (skilful means) whereas its companion tool, the bell which is a female symbol, denotes prajna (wisdom).
Together these ritual implements represent the inseparability of wisdom and compassion in the enlightened mindstream.
When the bell is being used with the vajra its use is varied depending on the ritual or the mantras being chanted. During meditation ringing the bell represents the sound of Buddha teaching the dharma and symbolizes the attainment of wisdom and the understanding of emptiness. During the chanting of the mantras the Bell and Vajra are used together in a variety of different ritualistic ways to represent the union of the male and female principles.

Mandala Offering.
Mandala mudra is a complex hand gesture (hasta mudra) used primarily in conjunction with Buddhist prayers and chants. It is often referred to as the mandala offering mudra, so-called because it represents the offering of the universe for the benefit of all.

The mandala mudra is performed to represent the offering of the entire physical universe to the enlightened Buddhas and teachers. Although this gesture is not actually made by the deities, it is extensively employed during the ritual visualization practice known as the 'mandala offering'.
During the ritual of the mandala offering the practitioner’s rosary is often coiled within the palms and around the raised ring fingers to represent the seven ranges of golden mountains and lakes that surround Mt. Meru.
