To purify offenses, monks and nuns must confess and “properly make amends for the offense according to Vinaya” (Tib. chos bzhin ’dul ba bzhin slar bgyi’o). This means, according to Kalyāṇamitra, that the monastic flawlessly follows the appropriate procedures spelled out in the Vinaya (F.326.a) . The proper procedure for making amends for offenses is described in The Chapter on the Restoration Rite (Toh 1, ch. 2, UT22084-001-002-699).
