The "nation sack" is a particular kind of mojo hand that is of special interest to women, because it is used to keep a man faithful and true. It so happens that the Nation sack is also of special interest to blues fans (many of whom are men) because it is mentioned in what may be Robert Johnson's finest song, "Come On In My Kitchen," recorded on November 23, 1936.
A nation sack is a special kind of mojo hand because it is a charm that is only carried by women. Its basic use is in spells of female domination over men or to keep a man faithful and make him generous in money matters. It is also more than that it also is to help empower the women that carry her nation sack and give her strength from within.
There are many kinds of mojo hands made and worn for love and fidelity, but during the 1930s, the use of the nation sack, by that name at least, seems to have been restricted to the region immediately around Memphis, Tennessee, and adjacent areas of Mississipi and Arkansas, where Robert Johnson spent his youth and young adulthood.
Nation sacks are filled with roots and herbs, oils, personal concerns among other goodies, plus instructions on how to accumulate the requisite "keepsakes and valuables" that make this bag so special.
