Preparation for the Tikkun of Fruit My teacher used to say that one should intend through eating the fruit to correct the sin that Adam committed with the fruit of the tree. Even though our intention is directed toward this end all the days of the year, a mitzvah is best when observed at its proper time, and this day is the beginning for fruit of the tree.
Repairing Adam's Sin One Blessing at a Time
