Vanditu Sutra is a short Prakrit verse used in the Svetambar Jain Pratikraman ritual. It is recited at the start of the rite to bow to the Panch Parameshti and to purify the mind before asking for forgiveness.

Digambar tradition does not typically use this exact Vanditu verse, though the spirit of bowing and seeking forgiveness remains. You can read more here
