Svasti) to our family, society, country and the whole world. It drives away all the evil forces of non-human beings, asuras, ghosts, yakshas and brings peace and happiness through the power of truth contained in the Buddha’s teachings.

According to the Mahamantranusarini sutra, Lord Buddha disclosed this dharani to Venerable Ananda in the city of Rajagriha. Lord Buddha instructed Ananda to recite this dharani to the people of Vaisali where they were having disastrous events. Later the Buddha himself visited the city of Vaisali and uttered the dharani of Mahamantranusarini thereby pacifying all the calamities. Nepalese Buddhists recite this dharani sutra of auspiciousness during the marriage ceremony, ordination and other auspicious occasions or ceremonies.
