The following is a prayer from the Bodhisattva Vow Ceremony as translated in the Nam Cho Daily Practice book from Palyul Ling International:
Prostrate to all the Tathagatas!
Prostrate to Bodhisattva Mahasattva Avalokiteshvara!
OM AH MO GHA SHI LA SAMBHARA SAMBHARA BHARA BHARA MAHASHUD DHA SATO PEMA BHI BHU KHE TE BU DZA DARA DARA SAMANTA AVALOKETE HUNG PHET SOHA (repeat 21 times)
May the Dharma of the perfection of moral self-discipline be thoroughly complete in my and all sentient being’s mind streams!
May all non-virtuous deeds and obstructions arising from discipline broken because of defilements be cleansed and purified!
May there be the fortune of discipline pleasing to the Aryas!
May I be placed in contact with the bliss of liberation not oppressed by defilement.
May proper moral self-discipline be without faults.
May moral self-discipline be possessed purely.
And the perfection of moral self-discipline without hypocrisy be completed!
May I be trained as a follower of all the Jinas,
Completing the conduct of Samantabhadra.
May my conduct of discipline be completely immaculate!
May my moral self-discipline have the sweet essence of being well-kept!
May my conduct always be without damage and without faults!
