A parallel has been drawn between these activities and the human condition according to the Biblical account of the expulsion from the garden of Eden. Refraining from these symbolically represents a return to a pristine state of re-attachment to the purity of Edenic existence, and symbolically therefore one avoids that which arose as a need only after the exile from Eden: The Eden account tells of God saying "thorns and thistles will grow in your way. . . the snake will raise its head (to bite you) and you will give your heel (to crush it)" and so in the new post-Edenic existence it became necessary to wear strong protective shoes, and so these are avoided on Yom Kippur (see article for specifics). The Eden account also states that as opposed to the automatic food and drink in Eden, it will be necessary to work for it "by the sweat of your brow", and so food and drink are refrained from on Yom Kippur, as well as washing, and the use of cosmetics to remove sweat or its odor etc. Similarly for the description of the post-Edenic relationship between man and woman, and so on Yom Kippur marital relations are avoided.
