After keeping the fast for 11 or 26 Trayodashi, the Vrat is concluded. It is also known by the name of Udyapan.
For the conclusion of this fast, Trayodashi Tithi is selected. One day before Udyapan, Lord Ganesha is worshiped. One night before, Kritan and Jagran are performed. Early in the morning, the Mandap is made and decorated with clothes and lotus flowers. A rosary of (108 times) "ऊँ उमा सहित शिवाय नम:" is chanted and hawan is performed. Kheer is used in Aahuti(offering) in Hawan.
After the Hawan is over, Aarti of God Bholenath is performed and Peace mantra(Shanti Path) is recited. At the end, two Brahmans are offered food. Also, alms are given as per ones capacity and blessing are taken.
