The conclusion of the standard ritual session of the Yasna has been the object of a study by Céline Redard and Jean Kellens entitled La liquidation du sacrifice (Y 62 à 72). It must be noted that the closing sequence of Y. 72, 6. corresponds to the opening one, usually numbered as Y. 0 in former editions of the Avesta. This fact is another evidence of the reorganization ritual that includes patent correspondences between opening and closing formulas.
