Vritham and Kappu Kettal. (Vedic)

As mentioned under Januvasam, the groom is still a brhamacharin in the ascetic garb. He is unshaved, uncut and supposed to lead a strict life as prescribed. His Guru when he was initiated in this life of penance is his father. So it is essential that before he gets married he has to take permission from his father (Guru) to end his Brhama Charya Vritha and marry and lead a life of a Grihastha.This function is Vritham. This function could also be performed in the groom's house before he departs to the bride's house for marriage.
The bride's family lead by the maternal aunt of the bride normally invites the groom with a pair of Paruppu Thengai Kutti.

During this time the groom's father makes him perform all the samskaras like namakaranam, Choulam, Annaprasanam etc which for some reason have not been performed and also make the groom do the duties as a brahmacharin which he has not performed like Khanda rishi tharpanam, Prajapatyam, Saumyam, Agneyam, Vaiswadevam etc and complete the samavarthana(life of a brhma charin). It is necessary according to religious beliefs that he has gained expertise in Vedas by this time.
Simultaneously a Raksha (Protection) in the form of a sacred string is tied in the wrist of the bride after reciting Vedic manthras to protect her from all evil spirits and also those Gandharvas, who were holding charge of her till then.
There is a custom of giving oil for bath, green gram for oil bath, sweets to eat after he takes a bath, to the groom before the Vritha by the aunt (Athai) of the bride. Nowadays this has been enlarged to include a shaving set, toilet articles like soap scent etc. Earlier days all these were supposed to be given during the early morning of the marriage at the groom's quarters with accompaniment of Nadaswaram etc. But nowadays, it is mostly handed over to the groom's party the previous night.. This is a purely Loukika custom.
