On Yom Kippur we take upon ourselves five afflictions, as taught in the Mishnah: abstaining from eating and drinking, bathing, anointing with oils, wearing shoes, and sexual intimacy (Yoma 8:1). Rabbi Ovadiah of Bartenura (c. 1445-1515) comments, as the Sages explain, that these prohibitions are derived from the five times that the Torah speaks of afflicting one’s soul on Yom Kippur. The number five is most significant when it comes to Yom Kippur. The Ba’al HaTurim (Rabbi Yakov ben Asher, c. 1269-1343) comments on Leviticus 16:14 that the five services performed in the Temple on Yom Kippur parallel the five prayer services that we recite on Yom Kippur (Arvit, Shacharit, Mussaf, Minchah, Neilah), as well as the five times that the Kohen Gadol would immerse in the mikveh, and the five souls of a person which are purified on this day. (For an explanation of these five souls, see A Mystical Map of Your Soul.)
