Sometimes transliterated as: Pavitraropana-vrata, PavitrAropaNa-vrata, Pavitraaropana-vrata
Pavitrāropaṇa-vrata means investing the image of a deity with the pavitra or the sacred cord. This ritual is supposed to set right all the defects and mistakes committed in all the pujās performed during that year. The putting on of the pavitra in the case of several gods is done on different days. It may be made of gold, silver, copper, silk or even kuśa or cotton thread. It must have knots, the maximum number being 100 and a minimum of 8.
