Telling of Pravaram (Vedic)

This is really an announcement about whom the bride is going to wed and whom the groom is to the people who have gathered there. The gothra to which the bride belongs, name of her paternal great grand father, her paternal grand father and her father are repeated in a sonorous loud tones by one priest. They ask the bride's father whether he agrees to protect the dharma of his family. He agrees. Then another priest similarly introduces the bridegroom by telling his Gothra, names of his paternal great grand father, paternal grand father and father. The groom Okays the information given and agrees for the marriage ceremonies. This is repeated thrice. Possibly this is a ritual to give a chance to the audience to tell any thing negative about the information repeated. This was necessary as the groom is a traveler in search of knowledge approaching the bride's father in a different village.
